Key failures can be tracked to two things, typically: 1.) Bad battery (don’t use cheap import batteries, they often don’t work)
2.) Broken inductor on the circuit board in the key Number two is not uncommon and is an easy fix. In the very “end” of the key, that is, the part that gets inserted into the slot on the car, is a small inductor that acts as the “antenna” that transmits the EIS code to the car’s receiver antenna, which is in the ring around the ignition switch. You can disassemble the key and resolder the broken wire on the inductor easily. Don’t ever use a third party to “code” a key for use in your EIS-equipped car. here’s why: In EIS, there are eight “slots’ in the memory for keys. If a third party clones a key, they effectively “lock” the slot that key was in and prevent additional keys from being added to EIS. So if that cloned key is lost, fails, whatever, you’re screwed. And each dealer handles these requests differently. Mine is pretty cool in that they’ll sell me a loose key. They want me to have the car present when they deliver the key, but that’s more for assurance that it works than security. I rarely do, but I try to accommodate them just to play nice. -D On Oct 5, 2023, at 1:25 PM, Andrew Strasfogel <[email protected]> wrote: My friend damaged his 1999 E320 key and was unable to start the car. The local dealer required that he present the vehicle in person with title/registration in order to make a duplicate key. Car was parked in a garage inaccessible to tow trucks, so there was no way to do this. Instead, he found a local computer tech wizard to repair the key. Success. Cost him under $50.
