NO WARRANTY IF YOU LOCK THIS UP. If you take it apart to install the transmission lock-up cam, do not "play" with it. Do not turn the key fully on until you have installed the lockout cam, rear electrical switch, and the cable for the transmission. You should only turn the steering lock to the first position for installation. NOT RETURNABLE IF YOU LOCK IT UP.

Product Details
The unit comes with the electrical switch NOT installed. You will need to use the "lock-out" cam from your existing assembly along with the three screws to mount the electrical switch. The lock-out cam goes between the switch and the steering lock.
NLA This is the last one we have. If your 1990 to 1995 GASOLINE W126, W201, or W124 key is starting to stick in the ignition pay attention! Better to replace the part before the key gets stuck, leaving you stranded. Because of the lockout feature in these cars, if you can not turn the key on - you can not even move the car off the road. This is the part you will need to fix the problem. We test it here in our shop. We found that if it is put together incorrectly, it can lock up, preventing the key from turning. That can destroy the new part!
Free aftermarket electrical switch included. We thoroughly lubricate the assembly with high-quality synthetic lube before putting it together and testing it in our shop. This lock has a threaded hole to attach the cable from the transmission that prevents starting the car unless the transmission is in park. If your car does not have this feature, this part WILL NOT WORK!
This part comes with installation instructions. You will need to remove the lower dash panel to access your steering column and lock clamp bolt. The instructions may not include specific instructions on removing your particular panel. There are many variables with the different models listed below. Please refer to your factory manual if you need help in removing your lower left side dash panel. Detailed instructions are included for installing the plastic cam assembly. This can be difficult to figure out and will cause jamming if not installed properly.
BONUS: You will receive Kent's on-demand video on emergency removal free of charge with the purchase of this ignition lock assembly. You will only need to use the procedures he shows in this video if you can not turn your key, your key is damaged, or you have lost it.
