Got my Car Stereo removal keys stuck!!

So, I was sure i was onto a winner the other day when i removed my Sony 6000CD from my Focus, to get the serial number, to then get the unlock code. I bought some removal keys for £4 from Ebay

This is where i started acting all special. On putting the unit back, i couldn't work out why it wouldn't stay in, and the keys wouldn't come out! For about 30 minutes i was trying to work out what the hell was going on, i must have looked like a right douche bag! At one point i even got some pliers and tried to put all my weight into pulling the keys out. Nothing worked, all that happened was a bit of swearing, some mangling of the keys, and some small blood loss!

The next day i suddenly had a thought.. and it was a good one, so i thought.  I'll get the pliers and try to force the keys out whilst the unit it out.  That didn't work either, and all i did was bend a few things i really shouldn't have done.  I'd managed to stuff it up so that the unit had gone back, and was secured by 1 clip, with all four keys stuck in - so now i was really screwed!

Today i applied even more brute force, and managed to get the unit back out. Then i discovered the full horror of my specialness. All i needed to do was gently press the clips in on the side of the unit, and remove the keys. Then just drop the unit back in, and it clipped neatly in place! Head in hands, i was ashamed of myself - but at least I've got a working stereo, and no keys stuck in the holes.

Don't be a douche bag like me!
