When buying a “new” car, you should always ensure that :-
A. All the keys you have been given work in the car at the time of delivery – not at time of demonstration. Nowadays, with comfort access, keyless entry and the like, that means that you need to have all keys away from the car and then approach and to try to open and start it with each key in turn; and,
B. That only keys which are in your possession will work to open and start your car.
This has been brought into sharp focus today by a customer who bought a 2015 Discovery 4 from a garage about ten miles away from his home, a couple of weeks ago. He was given two keys, but one didn’t work. The garage told him it’d just need a new battery. It neither unlocked the car nor started it.
A week later the car was stolen from his driveway by a thief with a working key. It’s definitely not a case of the keyless signal being intercepted, CCTV has the thief just walking up to the car and driving it away in under 10 seconds.
The car was a one previous owner, low mileage car and was sold by the previous owner with two keys.
I was able to tell him that the key that didn’t work in his car was, in fact, working correctly, didn’t need a new battery, and had it been correctly programmed into his car would have worked and that the “passwords” and coding on the two keys were so far apart that it was extremely unlikely that they were ever working on the same car.
It looks like this “dummy” key has been substituted for one of the good, working keys and the car stolen with one of the original keys, by somebody who either knew where it’d be parked or was *very* lucky to spot it.
One of the services we can provide and are often asked to do is to delete keys not in the owner’s possession. This is something you should always consider if you are not certain how many keys have been issued and where they all are.
You should also consider a Ghost immobiliser.
Unfortunately, I doubt my customer will ever see his Discovery again.
