'99 SL500 with only a single fob key. Had a non fob key cut which opens door, trunk and ignition but the car indicates "stert error" when trying to start the engine.
Any help would be appreciated.

It sounds like your car is not recognizing the transponder in the new key.

I just started having the same problem. I bought a '98 SL 500 last year, and it only came with one switchblade style remote, so I ordered one from my local dealer for $211 ! :eek:

Well this is where things get interesting. The trunk unlock button on the new remote stopped working. The warranty is for 12 months, and it's 13 months old :mad:

No problem I said to myself, I'll just go back to the original remote. WRONG ! Although the old remote locks and unlocks everything well, I get that "START ERROR" message when I put the key in the ignition. Re-initializing (as per the owners manual) did not alleviate the problem. :confused:

The plot thickens. I bought 2 new remotes from ebay. These had keys cut, but had never been used. (changing the key blade itself is very easy) Neither of these will "initialize" at all, and even if I swap the key blade from my working remote into one of these, I get that "START ERROR" message :( (I've already checked all the batteries)

Does any one know how to reprogram, re-initialize, re-synchronize these remotes/transponders ????????

I read in another thread that the newer style "smart keys" might need to be left in the ignition for up to an hour to be re-synchronized. Could that solve the problem ???

HELP US PLEASE !!!

Doesn't anybody know anything about programming / synchronizing remotes ! :confused:

My local dealership told me today there is no programming available for these remotes, I just have to order 2 new remotes. :eek:

That doesn't seem right. Just about every other remote in the world can be programmed. :mad:

Programming replacement keys SL500 '99

Using a tip from http://www.drdetailshop.com/remoteselect.htm I was finally able to program the replacement key, using Method 1 in the abouve URL. Started the car with the original key and immediately turned off and inserted the replacement MB non-remote key into ignition and restarted the car. Bought the blank key over internet and had a local locksmith cut the key. Total $ about $25.00 :)

Is there a transponder in the "Wallet Key" ? It seems too small to contain one :confused:

There are basicly two systems used by MB, the key fob with an infrared transmitter to lock and unlock, this remote would have key that would lock/unlock doors trunk and glove compartment. (some of those ) infrareds might work in opening the doors and might activate the ignition with the proper manual key but there is a sensor in the ignition switch. The Smart Key system uses a infra-red transmitter to lock and unlock the doors which is battery powered, the start function is handled by a independent inductive energy key that is powered by the ignition ring and the data is sent down a redundant data bus to the unlock and start functions.
The typical shipping configuration would be two full function remotes, that contain a mechanical key head also. The emergency remote only has the circuitry to activate the ignition, and also contains a mechanical key.
Those three take position 1,2,3, out of eight in row one, any additional keys move down the line. The replacement key will move into row 2 or 3, corresponding to the key it is replacing. A replacement removes the origional key forever, there can be no more than eight keys for any car out of a combination of twenty four.
A replacement key can take up to 90 minutes to communicate with the car, any remote needs to be coded by the MB PDC and can never be recoded by anyone. The code is kept by MB in their datbase.
If the system gets screwed up, new keys need to be ordered, the mechanical key can remain, and a cooresponding electronic learning key ships with them, which is a one time use. The remotes on E bay can be used for mechanical refurbishing since the entire "board" is removeable from the housing. The statements by the sellers are pure lies, the dealership can only disable remotes permanently, using the Star diagnostic software. The remotes are typically stolen by parking attendants, and people dont find the missing immediately since they are usually in the pouch.

If the key has any electronic elements (i.e. any buttons on it) you can only get it replaced at a dealer, I believe. Be prepared for some sticker shock.

Also be prepared to show proof of ownership as well as actually have the car at the dealer when you order the key as well as when you pick it up.

That is when you believe the

That is when you believe the seller on E-Bay, That whatever they are selling works or can be made to function by the dealer. The MB remotes on E-bay are either stolen from cars by valets, made in China, MB would never sell remotes with uncut keys, since only they control the codes. The key blanks are aftermarket and mostly brass, where the genuine blank made by Hoff is steel. The dealers dont cut keys anymore, they stopped in the mid 90s, the new keys are cut by computer controlled machines, not copied.
$25 to copy, Ebay purchase, doesnt work I am glad you saved some money. The old remotes have numbers 1 thru what ever, the same number can not be used at the same time, MB will use their database via the VIN #
