Think this might be a common subject but i haven't come across an answer yet

 

If i press down on the bonnet whilst turning the key to the left (before then turning to the right) it sometimes 'opens' but most of the time it feels like the key will snap.

 

Pushing down doesn't always help but is better when pushed, have had a spare standard key cut to avoid damaging the expensive remote keys.

 

Have lubricated the inner 'lock' with wd40 & tried greasing the end of the barrel going into the vehicle.

 

Any help appreciated.

very common problem on mk3 and mk4 mondeos

 

!Removed! poor design imo and they seize up like mad, You can free them off but its only a matter of time before they do it again, and theyre not user friendly either cos they are sealed units so to open them up you have to break them!! Frigging throw away society I hate it!! Why cant parts be serviceable!! Itll be cheaper for everyone then!! ARRGGH

 

Anyway I digress, get yerself to fords and buy a new one as thats the only way to cure it properly. Cost is around the £60 mark for the complete assembly

Do not put WD40 in the lock, as it is not a lubricant - its a penetrant.

WD40's lubrication properties are very short-lived. When that wears off in just a few hours, the WD40 will be sat in the lock, collecting all the dust dirt and filth that goes anywhere near it. The upshot is that your problem will soon return and be 10x worse than before.

To lubricate a lock i'd recommend a light oil or heat resistant PTFE lubricant.

There once was a time when WD40 was used (to try) to fix everything - how times have changed! :lol:

Get a new none-chipped key cut. This often cures the problem.
