Hi,this has been an on going issue almost ever since I have purchased the car but I think it is time to pay attention on it


initially, key worked fine at the door since I did not even have my fob yet. Once I programed a fob (perhaps not even related) , I realized I cant put the key all way in the keyhole anymore but it only takes like halfway

I want to know what went wrong and how to fix it.

note:WD40 did not work

 

WD40 is not suitable for locks. It was developed as a water dispersant (hence the name) and is not a lubricant. Over time it dries out which is probably why your lock has become inoperable.

Locksmiths use liquid Graphite, powder Graphite or Houdini Lock Lube as a lubricant for locks. For a partially seized lock, the liquid Graphite or Houdini spray will likely be the most effective in freeing the lock and then keeping it lubricated.

thanks,like I said before, learning something new everyday by owning a Jag

 

Try putting the lock lubricant (if you can get some) or a light oil like 3 in 1 on the tip of the key and then gently wiggling the key as you push it home.
Just pray that some joker hasn't pushed a matchstick into your lock.
