Has anyone disassembled a RR key fob (pictured)? I have a cut blade and need to get it into a FOB, that i plan to buy on ebay, but it seems like these FOBs are very touchy and hard to work with. Any advice would be most appreciated!
You are making a ghetto switchblade out of the LR key fob? 8~lionheart44 said:I have a cut blade and need to get it into a FOB, that i plan to buy on ebay
You are correct about that. Once the EEPROM chips in these fobs are mated to the immobilizer of a certain vehicle, they cannot be reprogrammed (by anyone, dealers with diagnostics or independents alike.) New fobs can, but what you often find for sale on eBay is used fobs with a new blank / uncut key attached to them, to make them look brand new... So it's an iffy purchase at best. If it turns out to be a used fob, the best you can do with it is opening the door through the emergency lock with the cut key blade, and programming the remote to lock/unlock doors etc., but you will not be able to start the car.opotamus said:I have been considering getting another key too, but I thought it is impossible to program a used fob...
Unlock the doors, yes. Start the engine, no. Trust me, there is no way a used fob can ever start the engine of a car it wasn't originally programmed for.lionheart44 said:I have also read the used fob can be "re-programmed" for my RR and be able to unlock doors and start the engine.
Face it Umberto, no matter how many times we post this info the legend of eBay will always win out over facts.umbertob said:Unlock the doors, yes. Start the engine, no.
