Hi, my astra vxr only came with the spare key, so im looking for a new flip key for it.

Ive seen second hand keys with new uncut blades for around £25 (meaning id need the blank cut to suit my locks, and the transponder chip coded to my car)

Can vauxhall do this? (if so what cost)
Can it be done with opcom?

Or will i have to get it done by an auto electricion/locksmith?

Cheers, Gary
