with the focus bonnet catch, you have to use the key to open it,stupid idea personally for example if you,ve got a problem that only shows when the engine is/has been running and obiovously you remove key to open bonnet and lose problem. just wondering does the bonnet catch need a coded key to open, because im thinking about getting a key cut but not coded to keep in the car just in case something like that happens, or if not can the coding bit be by passed for the bonnet catch

Key doesn't need to be programmed to anything to work the bonnet or door catches (manual). Just has to be cut correctly. Only things it needs programming for are the ECU (starting the car) and remote locking.
