I lost one of my Infrared remotes keys to my 92 400se. I stopped by the dealer to order a spare key and was told a replacement key is $179.00. Wow… ! I was also told I could not place an order for a “standard” master key. The only key replacement key I can order is one that is designed to install in the infrared remote.

I was also told the 92 infrared key has been replaced by Mercedes with a smaller (physical size) version with a keychain attachment. Since I have had to resynchronize the original infrared key in the past, I assumed other keys of the same type (infrared) could be programmed to work with my 400se by performing the resynchronizing procedure. So I began looking on ebay for a used infrared key designed to work with a S-Class mid 90’s model.

So I purchased an infrared Mercedes remote key of a later model S-Class on Ebay form the mid 90’s. I attempted to sync the remote but – it doesn’t work.

Does anyone know of other options? I guess I could just use the ebay remote (worthless) to hold a key made by the Mercedes dealership since the dealership can only order a key insert for the remote.

Thanks,
Russell
