Keyless Entry – Why?
Thursday, 4. July 2019
Many moons ago my dad bought a brand new Cortina and one of the options at the time was electric front windows. I asked if he was going to have the option as it looked pretty cool and his answer was – why? What problem did electric windows address? And besides which it was something else to go wrong.
Hand-cranked windows rarely went wrong and if they did a sharp bang on the inside of the door seemed to sort it out. So when you read daily of car crime increasing because of crooks being able to break into keyless car technology and nick cars and contents on an industrial scale I find myself asking the question – why? Why does the technology even exist?
What problem does keyless entry solve? I understand remote controls, one of the best things ever invented for TV’s and cars. With respect to cars, you no longer have to fumble in the dark to find a hole in which to stuff your key or breath on the door lock to defrost it enough to insert the key and gain entry on a frosty morning.
No more fumbling in the rain and with some diesels, remotely unlocking the car from a distance actually activates the pre-heaters which should be activated before starting the engine. So why this obsession with keyless entry? What is the problem it is solving over and above a remote key.
A remote key is capable of transmitting around a trillion variants of its generated code that allows the car to be locked/unlocked/boot opened etc. The only time the code can be accessed is when you push the button to transmit which is then changed the next time you lock or unlock the car making it incredibly difficult to break into the car.
On the other hand, a keyless device is transmitting constantly making it easy for crooks to harvest the code and unlock then start the car using a handheld computer device to gain entry. The fact is that it isn’t like my iPhone with either fingerprint or facial recognition you need to carry something so why not a remote key?
Personally, I don’t think my life will be in any way enhanced by having keyless entry so with a higher risk of theft and no doubt higher insurance premiums give me a remote control. My Audi is even more dopey. I have a remote control to open and lock the car and boot but when I’m in the car I have to press a button to start it with the remote control taking up space in one of my cup holders. Crazy!
In order to overcome the security issues faced by those with keyless entry I’ve scanned the solutions introduced by manufacturers and found that most either overcome the problem by using a Faraday bag that encases the signal or the remote can either be deactivated (a bit like pressing a button on a remote control) or it will deactivate itself if there is no movement. My solution is much easier, revert back to remote controls!
If you are concerned about keyless entry with your car some manufacturers have allowed for the keyless entry to be disenabled either yourself or by a main-dealer. Call their customer services or call into a dealer to find out. By Graham Hill
