Hi Rich, I'm glad to help you out. This part does not need to be programmed not unless you have an anti-theft system. The keys will work only with the cylinder and will not work for the doors and trunk. Luke has given step-by-step instructions on how to install this part. I hope this helps.

I'm not sure which vehicle that you are trying to use this lock cylinder for, but this will work for the w126, w124, and w201 chassis. You will have to take two pins that are about 100 mm long and the top portion and the bottom portion of the lock cylinder. Your lock cylinder must be turned to position one which is accessories, this is a must otherwise it will not come out. Once you have the key turned to lock position one, insert pins on the top and bottom and push all the way in with both they should release and the whole tumbler system should come out with the black sleeve around it. If you are unable to get the key into position one, try wiggling the key to make it turn into position one it may take some time but keep at it. If for any reason it does not turn into key position one by wiggling it unfortunately you might have to cut the face on the ignition cylinder. Once you are able to get the face to turn to position one then insert both pins to remove it, when you press both pins in they should release and it should just slide out. For the pins that are 100 mm long grind the ends to an angle so that way they will have ample sizing to slip underneath the clip to push it out to release the cylinder. And the ends that are ground down face the cylinder itself. Hope this helps!
