Do you know that?

 All ford locks having this key has a special mechanism in which a hardened cylindrical pin is placed on top of levers. This pin settles down only if correct key is inserted in the lock. This system helps in preventing the theft by allowing only legitimate key to work as even a small deviation from original key profile will lift this pin up and will prevent the lock from opening from any key other than original one. 

This mechanism also prevent forcible entry in the car as all the force applied on lock levers is directly transferred to this pin to lift it up instead of rotating the lock.


After careful inspection, we found that problem was with original key itself. Original key was worn-out so it was lifting the pin up. So we made a duplicate key from original one which finally solved are problem of jammed lock.

New key was able to rotate easily in the lock cylinder with-out lifting the pin up but when we tried the old key, problem persisted. 

In this special case the problem was due to worn out key, but we have found that same problem of jammed lock can also arise due to other factors.

Foreign particle in lockSometimes dust or other particles enter the lock causing this problem. This can be corrected by thoroughly cleaning the lock from inside
Sticky levers Sometimes moisture enters the lock which prevents independent movement of levers. You can take-out individual levers and clean it with a file.
