Switchblade Key
 

My key is malfunctioning (96 e 320) i have done the usual batteries,re synchronisation to no avail,the check light will not light and before i attack it i was wondering if someone could give me some disassembly tips,
Thanks,
Horse.

i never try to fix them, i always order them in for customers. if you do decide to take it apart then good luck with the spring that makes the key switch round! its a a bugger to get back in. there about 46 pounds +vat.
