When my classic Mini's were used as daily drivers I always used to fit Yale M69 Car/Van Security Deadlocks to both doors (half way down) and the boot, (as did companies like Wood & Pickett to their expensive Mini conversions). They were easier to fit to sliding window doors but could also be fitted into later winding window doors if you were careful to avoid interfering too much with the glass drop area/channels.
I can take some pictures of mine if anyone is interested.
Originally designed by Yale, the ‘M69’ is well-known within the security industry, where it is used to provide additional protection for motor vehicle doors. There are five lengths of lock cylinder to suit different door thicknesses, fitting into LH and RH standard cases. This lock was once fitted as original equipment to Rolls Royces.
- Operating bolt throws into striker in door post, and is held positively by action of lock cylinder.
- Key is turned through 360° to throw and withdraw deadbolt. Keys can be withdrawn in either mode. Bolt withdraws fully flush into case.
- With components separated, case is sunk into door-edge, mortice fashion. Cylinder is inserted through aperture cut in door panel and is engaged into top face of case. It is then screwed fully into position using two holes in lock face. Finally, set-screw on flange is tightened, and pegs may be driven into face to seal fixing holes. Striker is fitted to door-post, and a trimescutcheon is provided.
- Brass pin-tumbler lock with up to 1000 combinations. Unshuttered. Brass keys, nickel plated in ‘SX’ series
