Some on here think these keyless systems are unsafe, but forget that these are generally high-value vehicles that are nicked. The scroats certainly will target them if it is esy pickings. But I expect these thefts are a minority when considered as a simple percentage of stolen vehicles.
The scroats will take possession of other people’s property if given the opportunity – whether vehicles or other items.
Keyless systems are becoming more secure. Agreed, some systems are susceptible – some high value vehicles were easily nicked – Range Rovers were one marque that where the keyless system was very seriously flawed in the first implementations.
Some people don’t remember (or conveniently forget) that some vehicles were simple to break into when air bags were first fitted! Air bag deployment automatically unlocked the doors – so it didn't take long for some to realise that a heavy thump, with something like a lump hammer, on the vehicle towing point on some cars set off the airbags and unlocked the doors to allow simple and easy entrance. Not theft of the vehicle but easy to nick the contents – and an expensive repair job for the owner.
Go back further and car keys were a joke for some brands. I once borrowed a bunch of Ford car keys from my local police station (back when the station was manned in the evening (at least). I had locked myself out of my cortina and needed to gain access to drive home. I think it was about the second or third key that opened my car door.
One does not hear of many Rolls Royces being stolen – valuable, but not easy to sell on or break for parts!
If the scroats really want your car, they will take it. Do not think you are invulnerable, unless extensive steps are taken to avoid it. That will be whether they can drive or carry it away. Whether garaged or not – but obviously they will take the easiest pickings – they would get it one way or another. One even hears of ‘carjacking’.
While expensive mercs and rangerovers receive news coverage, the thousands of cars stolen by joy-riders are only local news – if that. Most insure their vehicles under a policy which includes theft. It is unfortunate that the policy cost will rise if a claim arises the policy, but it is generally much less than the loss of the vehicle.
I’m guessing Ady1 does not even own a vehicle with keyless locking? Just scaremongering? It won’t change much, however – the scroats will always be catching up on new security, but they will find ways to continue their thieving ways – be sure of that!
