Ford keys security - TOG
A while ago, my son bought an old 1992 high mileage Ford Escort with the old fashioned keys as a runabout. He says his car was recently driven without his permission as it had been found some distance from where he?d left it. But, because there was no obvious damage to the door lock or ignition, he hasn?t reported it. He?s been told that youths with old Ford keys can gain entry to and drive away various old Fords with high mileage and worn locks. Even a flat screwdriver will work with some! Is this true or just an old wives? tale?

Fords used to be notorious for worn locks where if it fitted in the lock, then chances are it'll turn it. And then there was the even older Fords (Cortina's, Mk1 & 2 Escorts for example) where it was rumoured that there were only 4 different keys made.

Maybe not far off the mark Dave. Company I used to work for had a fleet of 20 Cortinas delivered one day. The rumour that there were only a few locks was put to the test and everyone's key fitted at least three other cars.

Mk 1 Cavaliers were even easier. Just lift the drivers door handle and let it spring back. The locking button just popped up.

My old MG Midget could be started with the edge of a coin. Saved carrying keys I suppose.
