How do I programme the key for my Vauxhall Astra?
I recently bought a 2014 Vauxhall Astra GTC and one of the keys only partially works. It will unlock the doors and start the engine, but does not remotely unlock the doors. I have replaced the battery but that hasn't rectified the problem. When I start the engine with it, the radio displays a different selection of stored stations.
Assuming the fault is not with the circuit board, does it need re-programming and if so, how do I achieve that, please?

It's fairly simple to reprogramme the key:
1. Sit in the car with doors closed. Place the key into the ignition and turn to Pos II (lights on)
2. Now press the lock button on the key remote with the key still in the ignition for about 2 seconds
3. The central locking will now lock then unlock to show the remote control is now synchronized

I have a Nissan Qashqai (2012 model). The car key is well and truly stuck in the ignition. Can I still lock the car with the key in the ignition? Any advice on how I can free it?
I have lost the only key to my volvo v70 - the dealer wants £300+ for replacement. Are there alternatives?
One of our Land Rover Freelander 2 ignition keys does not recharge when driving and cannot be relied upon to open the car. We have asked our local dealer for help and they quoted £220 + VAT for a replacement...
