CHANGING MINI DOOR LOCKS
With a problematic multi-key locking system, Steve reveals what to do if you decide to change the locks on your Mini.
The MkII Cooper S has three locks. One for the ignition, one for the door and one for the boot. The passenger door is locked using a switch on the inside, there is no key lock for that door.
Over the years the locks on this ‘S’ had diverged, leaving three keys. The ignition key was a different shape but given a 50/50 chance of getting the right door or boot key, of course the chosen key was usually the wrong one.
Forty-nine years of use has also worn the mechanisms on these Minis, so the requirement to use the right key is reduced.
A trip to Mini Spares and a pair of matching barrels was procured. The design is that of the later Minis, so while they may not be the right option for the purist, for practical use, they are ideal.
The boot lock on these Minis wasn’t designed in a way which makes barrel replacement easy though, indeed they have the key number stamped in the shaft. My way around this was to use a Starlock washer, but you can also re-fix the steel cap by drilling the shaft and fitting a roll pin.
There are quite a few steps, so without further ado, I’ll don my best Edd China Grease Junkie gloves and get going!
