On a e39 you are going to have troubles with the EWS (driveaway protection system) On cars with EWS there is a transponder chip in the key which the vehicle's systems need to see in order for the car to start. So basically the only way to do a remote start is to add a second key under the dash along with a second ring aerial. This will work but keep in mind that it totally bypasses the vehicles security system which is 1 of the best systems on the market.
BillB: If I remember correctly, it retailed around 400 installed, but as DT said the transponder module will add around 75-100 installed. Plus the loss of a key.
DT: The newer DEI modules for the key have a setup on them so it only becomes active whenever it receives a "start" signal from the remote start so the factory security stuff still remains in tact. You still lose a key though. If he doesnt have one, it could make the install a little more pricey.

Ok so I got a question, I have the same car, a 97 528i, mine came with a key that IS the remote. If I get this remote start system can I start my car with the remote start system or what? Im confused just a little haha
