Hi All, new to NAM.. So i picked up an r53 beggining of this year and i have recieved one key which does not have remote buttons etc..

Would it be possible to say buy an r53 key off ebay with the circuit board, then swap the transponder over from my current key to the ebay key. Is it as simple as holding down lock button then unlock 3 times to code the unlock/lock setting?

Dont want to have to spend hundreds for a key that unlocks & locks my door.

Any help would be greatly appreciated !
