Yes, flick the old one out with a pointed item and press the new one in.
Is it that easy to replace the push buttons and battery?
No need to reset/re-programme key fob or anything? Only checking as I need to do mine but only got one key and don't have EKA code (note to self find out what it is and how I get it).
Wammers thanks.
Have a wee bag of bits to refurb but was holding off for some reason. Seeing that question made me understand why
