<p>A <b>remote keyless system</b> (<b>RKS</b>), also known as <b>remote keyless entry</b> (<b>RKE</b>) or <b>remote central locking</b>, is an <a href="Electronic_lock" title="Electronic lock">electronic lock</a> that controls access to a building or <a href="Vehicle" title="Vehicle">vehicle</a> by using an electronic <a href="Remote_control" title="Remote control">remote control</a> (activated by a handheld device or automatically by proximity).<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> RKS largely and quickly superseded <i>keyless entry</i>, a budding technology that restrictively bound locking and unlocking functions to vehicle-mounted keypads.

</p><p>Widely used in automobiles, an RKS performs the functions of a standard <a href="Key_(lock)" class="mw-redirect" title="Key (lock)">car key</a> without physical contact. When within a few yards of the car, pressing a button on the remote can lock or unlock the doors, and may perform other functions.

</p><p>A remote keyless system can include both <i>remote keyless entry</i> (RKE), which unlocks the doors, and <i><a href="Remote_starter" title="Remote starter">remote keyless ignition</a></i> (RKI), which starts the engine.

</p><p>Numerous manufacturers have offered entry systems that use door- or pillar-mounted <a href="#Keypad_entry_systems">keypad entry systems</a>; touchless <a href="Passive_entry" class="mw-redirect" title="Passive entry">passive entry / smart key</a> systems that allow a key to remain pocketed; and PAAK (Phone as a Key) systems.

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>Remote keyless entry was patented in 1981 by Paul Lipschutz, who worked for Nieman (a supplier of security components to the car industry) and had developed a number of automotive security devices. His electrically actuated lock system could be controlled by using a handheld fob to stream infrared data. Patented in 1981 after successful submission in 1979, it worked using a "coded pulse signal generator and battery-powered infra-red radiation emitter." In some geographic areas, the system is called a PLIP system, or Plipper, after Lipschutz. Infrared technology was superseded in 1995 when a European frequency was standardised.<sup id="cite_ref-Mills2014_2-0" class="reference"><a href="#cite_note-Mills2014-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Torchinsky2021_3-0" class="reference"><a href="#cite_note-Torchinsky2021-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p><p>The remote keyless systems using a handheld transmitter first appeared on the French made <a href="Renault_Fuego" title="Renault Fuego">Renault Fuego</a> in 1982,<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> and as an option on several <a href="American_Motors" class="mw-redirect" title="American Motors">American Motors</a> vehicles in 1983, including the <a href="Renault_Alliance" title="Renault Alliance">Renault Alliance</a>. The feature gained its first widespread availability in the U.S. on several <a href="General_Motors" title="General Motors">General Motors</a> vehicles in 1989.

</p>

<div class="mw-heading mw-heading3"><h3 id="Function">Function</h3></div>

<p>Keyless remotes contain a short-range <a href="Radio_transmitter" class="mw-redirect" title="Radio transmitter">radio transmitter</a>, and must be within a certain range, usually 5–20 meters, of the car to work. When a button is pushed, it sends a coded signal by <a href="Radio_wave" title="Radio wave">radio waves</a> to a receiver unit in the car, which locks or unlocks the door. Most RKEs operate at a <a href="Frequency" title="Frequency">frequency</a> of 315 MHz for North America-made cars and at <a href="LPD433" title="LPD433">433.92 MHz</a> for European, Japanese and Asian cars. Modern systems since the mid-1990s implement <a href="Encryption" title="Encryption">encryption</a> as well as rotating entry codes to prevent car thieves from intercepting and <a href="Spoofing_attack" title="Spoofing attack">spoofing</a> the signal.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> Earlier systems used infrared instead of radio signals to unlock the vehicle, such as systems found on Mercedes-Benz,<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> BMW<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> and other manufacturers.

</p><p>The system signals locked or unlocked status through discreet signaling — by the lights, horn, or both. A vehicle might use a chirp system: two beeps on driver door unlocking, four beeps on unlocking of all doors, a long beep for the trunk or power tailgate or a short beep on locking and arming of the alarm.

</p><p>The functions of a remote keyless entry system are contained on a <a href="Keychain#Key_fob" title="Keychain">key fob</a> or built into the <a href="Ignition_system" title="Ignition system">ignition</a> key handle itself. Buttons are dedicated to locking or unlocking the doors and opening the trunk or tailgate. On some minivans, the power sliding doors can be opened/closed remotely. Some cars will also close any open <a href="Power_window" title="Power window">windows</a> and roof when remotely locking the car. Some remote keyless fobs also feature a red <a href="Panic_button" title="Panic button">panic button</a> which activates the <a href="Car_alarm" title="Car alarm">car alarm</a> as a standard feature. Further adding to the convenience, some cars' engines with remote keyless ignition systems can be started by the push of a button on the key fob (useful in cold weather), and convertible tops can be raised and lowered from outside the vehicle while it's parked.

</p><p>On cars where the trunk release is electronically operated, it can be triggered to open by a button on the remote. Conventionally, the trunk springs open with the help of <a href="Hydraulic_cylinder" title="Hydraulic cylinder">hydraulic struts</a> or <a href="Torsion_spring" title="Torsion spring">torsion springs</a>, and thereafter must be lowered manually. Premium models, such as SUVs and estates with tailgates, may have a motorized assist that can both open and close the tailgate for easy access and remote operation.

</p><p>For offices, or residences, the system can also be coupled with the security system, garage door opener or remotely activated lighting devices.

</p>

<div class="mw-heading mw-heading3"><h3 id="Programming">Programming</h3></div>

<p>Remote keyless entry <a href="Security_token" title="Security token">fobs</a> emit a <a href="Radio_frequency" title="Radio frequency">radio frequency</a> with a designated, distinct digital identity code. Inasmuch as "programming" fobs is a proprietary technical process, it is typically performed by the automobile manufacturer. In general, the procedure is to put the car computer in 'programming mode'. This usually entails engaging the power in the car several times while holding a button or lever. It may also include opening doors, or removing <a href="Fuse_(automotive)" class="mw-redirect" title="Fuse (automotive)">fuses</a>. The procedure varies amongst various makes, models, and years. Once in 'programming mode' one or more of the fob buttons is depressed to send the digital identity code to the car's onboard computer. The computer saves the code and the car is then taken out of programming mode.

</p><p>As RKS fobs have become more prevalent in the automobile industry a secondary market of unprogrammed devices has sprung up. Some websites sell steps to program fobs for individual models of cars as well as accessory kits to remotely activate other car devices.

</p><p>On early (1998–2012) keyless entry remotes, the remotes can be individually programmed by the user, by pressing a button on the remote, and starting the vehicle. However, newer (2013+) keyless entry remotes require <a href="Car_dealership" title="Car dealership">dealership</a> or <a href="Locksmith" class="mw-redirect" title="Locksmith">locksmith</a> programming via a <a href="Computer" title="Computer">computer</a> with special software . The <a href="Infrared" title="Infrared">Infrared</a> keyless entry systems offered user programming, though <a href="Radio_frequency" title="Radio frequency">radio frequency</a> keyless entry systems mostly require dealer programming.

</p>

<div class="mw-heading mw-heading3"><h3 id="Passive_systems">Passive systems</h3></div>

<p>Some cars feature a passive keyless entry system. Their primary distinction is the ability to lock/unlock (and later iterations allow starting) the vehicle without any input from the user.

</p><p>General Motors pioneered this technology with the Passive Keyless Entry (PKE) system in the 1993 Chevrolet Corvette. It featured passive locking/unlocking, but traditional keyed starting of the vehicle.

</p><p>Today, passive systems are commonly found on a variety of vehicles, and although the exact method of operation differs between makes and models, their operation is generally similar: a vehicle can be unlocked without the driver needing to physically push a button on the key fob to lock or unlock the car. Additionally, some are able to start or stop the vehicle without physically having to insert a key.

</p>

<div class="mw-heading mw-heading3"><h3 id="Security">Security</h3></div>

<p>Keyless ignition does not by default provide better security. In October 2014, it was found that some insurers in the United Kingdom would not insure certain vehicles with keyless ignition unless there were additional mechanical locks in place due to weaknesses in the keyless system.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>

</p><p>A security concern with any remote entry system is a <a href="Spoofing_attack" title="Spoofing attack">spoofing</a> technique called a <a href="Replay_attack" title="Replay attack">replay attack</a>, in which a thief records the signal sent by the key fob using a specialized receiver called a code grabber, and later replays it to open the door. To prevent this, the key fob does not use the same unlock code each time but a <a href="Rolling_code" title="Rolling code">rolling code</a> system; it contains a <a href="Pseudorandom_number_generator" title="Pseudorandom number generator">pseudorandom number generator</a> which transmits a different code each use.<sup id="cite_ref-Brain_9-0" class="reference"><a href="#cite_note-Brain-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> The car's receiver has another pseudorandom number generator synchronized to the fob to recognise the code. To prevent a thief from simulating the pseudorandom number generator the fob <a href="Encryption" title="Encryption">encrypts</a> the code.

</p><p>News media have reported cases where it is suspected that criminals managed to open cars by using <a href="Radio_repeater" title="Radio repeater">radio repeaters</a> to trick vehicles into thinking that their keyless entry fobs were close by even when they were far away (<a href="Relay_attack" title="Relay attack">relay attack</a>),<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> though they have not reported that any such devices have been found. The articles speculate that keeping fobs in aluminum foil or a freezer when not in use can prevent criminals from exploiting this vulnerability.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup>

</p><p>In 2015, it was reported that <a href="Samy_Kamkar" title="Samy Kamkar">Samy Kamkar</a> had built an inexpensive electronic device about the size of a wallet that could be concealed on or near a locked vehicle to capture a single keyless entry code to be used at a later time to unlock the vehicle. The device transmits a jamming signal to block the vehicle's reception of <a href="Rolling_code" title="Rolling code">rolling code</a> signals from the owner's fob, while recording these signals from both of his two attempts needed to unlock the vehicle. The recorded first code is sent to the vehicle only when the owner makes the second attempt, while the recorded second code is retained for future use. Kamkar stated that this vulnerability had been widely known for years to be present in many vehicle types but was previously undemonstrated.<sup id="cite_ref-RollinCode_12-0" class="reference"><a href="#cite_note-RollinCode-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> A demonstration was done during <a href="DEF_CON" title="DEF CON">DEF CON</a> 23.<sup id="cite_ref-DC23_13-0" class="reference"><a href="#cite_note-DC23-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup>

</p><p>Actual thefts targeting luxury cars based on the above exploit have been reported when the key fob is near the front of the home. Several workaround can prevent such exploits, including placing the key fob in a tin box.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> A criminal ring stole about 100 vehicles using this technique in Southern and Eastern Ontario.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup>

<div class="mw-heading mw-heading2"><h2 id="Keypad_entry_systems">Keypad entry systems</h2></div>

<p>Prior to remote keyless systems (RKS), several manufacturers offered keypad systems which did not allow "remote entry" per se, but allowed a user to enter a vehicle without a key by entering a code on a multi-button keypad on the driver door or pillar—to unlock the driver door. Subsequent code presses could unlock all doors or the trunk—or to lock the vehicle from the outside.

</p><p>A keypad system can enables tiered or time-restricted permissions, i.e., the code allowing access to the vehicle but not starting the engine. The code, while factory programmed, can subsequently be user programmed and if shared, can be easily changed to prevent subsequent vehicle access. The system also allows a user to leave the ignition key in the vehicle, for later retrieval—including by another user sharing a unique entry code. Two hikers, for example, can leave the keys in the glove box, lock the door, and either hiker can return later to access the vehicle via their own code. The keypad also allows a user to walk away from a running vehicle, e.g., to warm up the vehicle in cold weather, returning to unlock the vehicle by the keypad.

</p><p>Ford introduced its proprietary keypad system with physical buttons for model year 1980—on the <a href="Ford_Thunderbird_(eighth_generation)" title="Ford Thunderbird (eighth generation)">Ford Thunderbird</a>, <a href="Mercury_Cougar#Fifth_generation_(1980–1982)" title="Mercury Cougar">Mercury Cougar</a>, <a href="Lincoln_Continental_Mark_VI" title="Lincoln Continental Mark VI">Lincoln Continental Mark VI</a>, and <a href="Lincoln_Town_Car" title="Lincoln Town Car">Lincoln Town Car</a>—marketed initially as the <i>Keyless Entry System</i>, later as <i>SecuriCode</i> and most recently as the <i>SecuriCode Invisible</i>, the latter where a <a href="Touchscreen" title="Touchscreen">capacitive touch pad</a> replaces physical buttons and illuminates on contact, remaining otherwise hidden. Because of its unique access features and its popularity, Ford offered a keypad system on 90% of its vehicles as of 2019<sup id="cite_ref-90%_17-0" class="reference"><a href="#cite_note-90%-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> and continues to offer it as of 2025, more than forty years after its introduction. Notably, Ford's other systems have not displaced the keypad system; rather Ford continues to offer its keypad system alongside its fob-operated RKS, its <a href="Passive_entry" class="mw-redirect" title="Passive entry">passive entry/smark key</a> systems,<sup id="cite_ref-template_18-0" class="reference"><a href="#cite_note-template-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> and most recently its App-driven "Phone as a Key" systems.

</p><p>The sixth generation <a href="Buick_Electra" title="Buick Electra">Buick Electra</a> (1985–1991) featured a sill-mounted keypad for model years 1985–1988, superseded in 1989 by GM's remote keyless system.

</p><p><a href="Nissan" title="Nissan">Nissan</a> offered the a keypad technology on the 1984 <a href="Nissan_Maxima#PU11)" title="Nissan Maxima">Maxima</a>, <a href="Nissan_300ZX#Z31" title="Nissan 300ZX">Fairlady</a>, <a href="Nissan_Cedric#Y30" title="Nissan Cedric">Gloria</a> and <a href="Nissan_Cedric#Y30" title="Nissan Cedric">Cedric</a>, essentially using the same approach as Ford, with the addition of being able to roll the windows down and open the optional <a href="Moonroof" class="mw-redirect" title="Moonroof">moonroof</a> from outside the vehicle on the door handle installed keypad on both the driver's and front passengers door as well as roll the windows up, close the optional sunroof and lock the vehicle.
