Will the locks in my 2014 GSA boxes be codeable ? My dealer is saying not all locks can be changed
The answer is both yes and no.
You may easily remove the barrel from each of the locks.
But there are two types of barrels, the recodable ones, and the ones you may not recode.
The recodable ones will allow the keying plates to be pulled out and be replaced, the only thing holding the plates from popping out when you pull out the barrel is the key, that holds the plates from leaving the barrel (they are spring loaded)
The none codable ones have a small pin that is parallell to the key and penetrates through all the plates. The plates are still push in the same way as for the codable ones, but once the barrel is coded for a key, BMW put the pin in from the face of the barrel and then they put the chromed front back on the barrel.
I don't think BMW wants the dealer to do it, but if you want to recode the non codable ones you simply remove the front chromed cover and pull the pin out. You may then remove the plates as needed, and if you put the cover back on without putting the pin back in the barrels will remain recodable, or you fit the proper plates and lock them by putting the pin back in prior to pushing the front cover back on.
