Hi guys - I am having increasing problems getting my key in and out the lock on the door. I have a 2011 petrol 1.4 i30. Increasingly, it does not go fully in and has to be pushed before it enters fully and can turn in the lock, Is this serious, what could be causing it, has anyone else had this issue and what may need doing to fix it ? I was thinking that a spray of WD40 may fix it but haven't tried that yet. All assistance gratefully received ! Thanks  :victory:

Keys (problems getting my key in and out the door lock)

Welcome Robert,

I'm a bit confused? Doesn't your model have remote central locking? Personally i prefer graphite powder as a lock lubricant but it can stain your clothes if too much gets on the key. WD 40 is definitely an option as well of course.  Either of these should do the trick.

I feel like my arms have been cut off or that I'm visiting a third world country if i have to insert a key in an ignition lock.

I can't recall the last time i used a key in a door lock to enter a car.  :crazy2:

I use one regularly.
A special cut, non transponder blank which can go in the surf on a cord around my neck.
I used one for eight years with my FD. Despite worrying about the effects of salt, I never had an issue.
I much prefer graphite powder in locks of any kind rather than WD40, but not for any scientific reason.

I put little bit of gun oil once or twice a year. It stays on a bit better than WD-40.

I'd be motivated to sort out the transponder issue, Robert. It's so much better than tempting fate with use of mechanical means over wireless, especially for the older cars, regardless of model. I think some posts here go into it.

Even if you use the key to manually unlock the door, doesn't the transponder chip have to work properly to be recognised by the immobiliser? Did your car not come with 2 keys?

If the key isn't unlocking the car, it could be a number of things wrong with it, maybe the transmitter in the key fob or the receiver in the car. Either way, I would try and get the remote locking working. When I collected my current car I found one of the keys didn't work, so the dealer arranged for an RAC guy to come out in his van and make me a new key on the spot.

If you want to persist with using the key here is a YouTube video comparing various lubricants for pin-tumbler locks. Generally, oil-based lubricants can eventually gum up the lock and attract dirt.

Hi, do you not use the key fob to unlock the door? WD40 won't do it any harm but it might not work. You have nothing to lose though  :)

The key has a profiled slot cut in it, so I don't know what the lock structure is like inside, but I imagine when you're pushing the key in it's pushing against spring-loaded pins. If the key hits an obstruction that stops it being fully inserted I can only think it's one of those pins that is stiff, or something in the actual keyway that is obstructing it. If it was the latter, I would expect it to block the key all the time, whereas you can get your key in, it just needs a bit of force.

If a dry graphite or PTFE lubricant won't free it up, you may have to take the door lock out and see if you can clean out the lock barrel, if it can be removed from the rest of the lock. When taking it apart be meticulous about what you're doing so you know how to put it back together. It may suddenly fly apart in a shower of springs.

I would still try and get the remote locking working.

Car key locks can suffer from cold, salt and dirt accumulation over time. I used a little WD40 on old Corrola key lock years back and it freed it up nicely. Use a tissue or rag to wipe the key of the dirty residue each time after inserting and removing. The idea is to remove dirt rather than flood the lock.
I am aware WD40 has its critics and there maybe better products for locks, but it is something many of us may already have in our garages and I can say it worked for me.
Agree with others about getting the remote back working. What about your spare key? Dead key battery?
