My lock was evidently slightly frozen, not enough to stop me getting the key in but enough to snap the fking key in two when I tried to unlock it! I didn't use a huge amount of pressure, and i partially blame the poor quality metal of the copy non-OEM key!

Anyway, does anyone have any top tips on how to get the broken part out, if this is at all possible? I'd rather avoid drilling the whole thing out to replace the barrel and having different keys for the drivers door and ignition.

Tweezers, sharpened on an oilstone if necessary. Make sure the key isn't frozen in when you try it obviously biggrin

I have no idea at all if this is possible but it might be possible to push it out from the back if the key-hole goes all the way through. Again, no idea if this is possible...

something thin and pokey inserted into the lock with a blob of superglue on the end. Wait a couple of mins and pull it out

Thanks for the ideas, but I like the sound of this superglue one, wouldn't have thought of that!

I'd be surprised if it works. Super Glue is rubbish on metal and door locks hold quite tightly. You also want to be very careful putting superglue IN your locks!

Got any barbed fishing hooks? Straighten one out and you may be able to pull the piece of key out by holding the straightened hook with pliers.

Two precision screwdrivers, the very thin ones, can sometimes be slid along the blade of the key enough to clamp the key and pull it out.

Depending how much of the key you can get at, needle nosed pliers with the ends milled may work.

Obviously make sure the lock is thawed and that the key is not turned in the cylinder before you try to remove it. smile

I had this happen with my Eunos roadster. IIRC - it was a while ago - I think I just used tweezers or maybe I used some gaffer tape on the end of a tiny screwdriver.

Failing that why not just lift your MX5 up on its side and shake it a bit? hehe

Thanks again guys, the car is currently stranded at the other side of Glasgow (under a watchful eye) due to the horrific weather up here, so I haven't had a chance to try the suggestions, but I've managed to get hold of a tool kit from my old man (Aldi special) that has 3 different pairs of thin nosed pliers and some heavy duty tweezers so I don't need to nick my good lady's, I think I'll try them before going crazy with glue and the like.

I'm not in the AA, I drive a reliable Japanese sports car, why on earth would I need an AA membership? wink

In terms of lifting it up and shaking it, I've been driving it through salted roads for a few weeks now, I'd be worried about bits falling off hehe

One more idea - suction, just don't get your lips stuck to the car in this weather! hehe No, I mean try a powerful vacuum.

Happened to my father many years ago. He put a blob of superglue on the tip of the free section of the key, popped it in the lock, married it up with the stuck section, then withdraw the whole key.

Superglue is useless for sticking a key together in the long term, but it should offer enough adhesion for you to remove the piece that's stuck in the lock. You can then get a new key cut and throw the broken one away.

spray the lock with lube first (to keep it from freezing up on you), then take a coping saw blade and cut the ends off, then stick it into the lock next to the key, twist the blade so the barbs are sticking into the key, then pull the key out. Sounds easier than it actually is.

J.P.W.

Good luck, OP. Do let us know how you get on.

OTOH, you reckon the quality of the metal might be a problem. OE keys aren't any better - mine's got a crack in it and is good for nothing apart from providing a template for replacememts wink.

Thread update as requested, happy days, found a really handy pair of hook nosed tweezers I forgot I had, pulled it out enough to grab with some Aldi special long nose pliers, result!
