Engine immobilizer activated by encoded key. You must have the key in the ignition slot for the car to start. Bypass the starter-kill all you want, you have to bypass the encoded key anti-theft system.

BTW, it can be done, but it's tough. The switchblade key is not as robust with anti-theft as the SmartKey, but it's pretty good. We did an ML with the same system and created a key embedded to fool the anti-theft, and the AMM computer "figured" out what we were up to (since it found two keys at the "same" time) and WROTE OUT all the keys to activate the anti-theft. You don't want to know what it cost to fix. Ugly.

You can take one of you existing keys and install it inside the column to fool the encoding system, but that won't work very well. The computer will see two keys and react to a "theft" situation.

I've been out of the biz for a few years, but I highly doubt MB has released the encoding for the Switchblade key. You might be able to buy an aftermarket module if they have, but MB is pretty picky about that stuff. Some company might have broken the encoding and produced their own bypass module, and that is your best bet. Might be pricey as MB's are low volume and not having MB's cooperation in the encoding would make it expensive to initially crack the code alogorithim.
