Hi there,

I am looking to buy a couple of spare keys, from research I believe my keys are HU101 with a 4D60 chip, but I don't know if it's 40 or 80 bit, the dealership couldn't tell me either.

Is there any way to find out or do I just have to buy both? I have been told it's just the BF key but once again 40 and 80 bit variations are available.

Thanks for your help
