I recently left my 2007 V70 D5 with an airport parking company - who managed to lose my key! [I have a spare set of keys, and now have the car back, and am able to drive it].
The parking company have said they will pay for a replacement key (about 200 UKP) but I am concerned that if the original key has fallen into the hands of a villain, the car could be susceptible to theft.
My Volvo dealer says that each key is individually encoded to be recognised by the car, so that they can - in effect - de-activate the lost key and activate the new one. Apparently when you insert the key into the ignition switch, data is read off the key which has to be valid before the engine will start. The dealer says that the old key would still open the door - presumably by actually inserting the key into the lock rather than using the remote control (which hopefully *wouldn't* work).
I'm not sure how paranoid I had ought to be about all this. The chances are that there is a label attached to the keys (by the parking company) on which is written the registration number (licence plate number for N. American readers) of my car. Although the registration number database in the UK is not publicly accessible, it's not all that difficult for a villain to find out the name and address of the owner of a car once they know the registration number. So my car could, in theory, receive a visit from a villain in possession of my old key when it's parked on my drive. The villain would be able to open the doors and steal the contents - and open the bonnet (hood) - and possibly hot-wire it to drive it away. [I assume that the key would still turn in the ignition, and release the steering lock even if it wouldn't start the engine].
Are there any Volvo security experts out there who would care to offer an opinion on the risks which I face? Presumably I would be totally safe if all the doorlocks and ignition lock were changed and totally new keys provided - but that would be extremely expensive, and I may have difficulty getting the parking company to pay for it.
Your informed comments will be most welcome.
TIA.
