Type2Teach, do you have any tips for disassembling the key fob? I've gotten the battery cover off no problem, but the rest of the case feels pretty solidly secured. I don't want to completely destroy my last OEM key.

I dont know if my one and only key fob is my current problem. I was able to start the van to make sure the new lamps I installed worked. When I came back out to the van to go for drive, it would not start. acted a bit like battery was low. I checked and VOM read 12.5V. At some moment, I had pressed the key fob buttons, which I normally dont do. Not sure if fob is my issue. I turn the key and dash goes blank like battery is dead. I jump the car. all of the systems such as hazard lights and headlights work. Turn key to second position as if to start. All of the normal lights come on. but when I try to start the van, instrument lights flash a few times and no starting noise is made. There had been a message on the screen about start error. Fuses all look good. PO had some odd ones in there. I took those out. Radio, cig lighter and right rear lamp. Dont think they would prevent van from starting. Something is a preventing from starting.
Once I disconnect the helper car jumpers, van goes back to very odd behaviors of appearing to be low on battery. Again battery after being assisted for 20 mins, shows 12.6V on the VOM. Yet when putting the key into the ignition behaves very strangely. All lights on the instrument cluster go blank.

Prior to these issues I had run the van fine. I also did remove the fuse block on the battery to clean up a wire problem the PO had left unrepaired. Could my problem have been a hapchance with the ignition switch? Did I trigger something when I removed the fuse block on the battery? Do I need to get a lock smith out to fix the imoblizer issue? I only have the one key. It is also quite worn down.

Edit- Daveisdave made a good point that I forgot to mention- on *some* sprinters (like Daveisdave's) you will need to file down the part of the new key you hold with your thumb and finger. For some reason, the key won't seat deep enough in the ignition. I don't have a photo of any of the keys I've had to file down, but you can see on the original key that the flat shaft between the black fob and the cut part is a slight bit longer than the flat part on the new key. I'll try to find someone who I have had to file down their key and post a photo of it.

My last functioning key fob broke last week. So that I now had 3 broken fobs with detached keys. I searched arround, and found replacement fob cases with blank keys on E-bay


Mercedes 2-Button-Flip-Remote-Key-Shell-Case

When they arrived, I split open my original fobs, removed the chip, and the remote door lock control board, and transferred both into the new fob cases. then I also took the cut keys out of the broken old fobs and replaced the blanks that had come with the new fob cases. Snapped them together with a little gel super glue, and now I have three fully functional fob keys with remotes.

Be really careful with the button springs for the key flip. I had one get away, and had to hunt on the floor for it for quite some time.

Does anyone know somewhere I can get mb17 keys quickly? Looks like ones on amazon are in China! Somewhere local? Tried dodge dealer, Walmart, lowes, ace, do it best. No blanks

Prowl independent locksmiths... there is also a VW key that fits (at least as a mechanical)
(i'll add its number here if i can dig it up)

From my dusty records, for T1N Sprinters:
ILCO MB-17, DL YM19 <-- RFID
Bianchi BYS15TK1 <-- clonable RFID
Ilco blank # 61-6337 (don't know if it has RFID)

The last mechanical key i found was at a small kiosk-in-shopping-mall key-cutter's.

I took a pick of one of the re-cased key fobs. I think it turned out quite nicely, and works great.

This one had been sitting in the kitchen junk drawer for the last 3 years so the key itself still has electrical tape / dirt residue on it from the old failed repair

Here is a link to the two keys I bought for my 2006. Locksmith doubted he could program a key for a Mercedes and was surprised when his machine read the one key fob I had. He programed the two keys and cut them. They work just fine. May not work for newer years.

You are correct about them not working in "newer years" (2007+)... the metal part of the key is a completely different shape ("warding" as they say in the trade) and cutting technology.

Great success finally getting functional keys for 2002 Freightliner Sprinter. Ordered the chip key blanks from ebay (5 for $40). The blanks were sold as 2003-2006 Dodge Sprinter keys but they worked fine in my 2002 model year (built Nov 2001). Got them cut and cloned at Ace Hardware of South Walton (Walton County Florida). None of the locksmiths in the area could do it, and the other three Ace Hardware stores were not equipped for chip keys, but Ace of South Walton handled it quickly and economically. My 2002 Freightliner was not in their chip key computer system, but doing it as a 2003 Dodge Sprinter worked fine. Since many Ace Hardware locations don't realize they can do it, convince them to try, and it works fine. 5 out of 5 successful keys work in door and ignition.

Caution: My key blanks were longer than they needed to be. Make sure the key is cut from the shoulder rather than the tip so you don't end up with a key that is too long.

Back to the glue the chip subject. Very little disassembly is needed for the hack.

If you epoxy the chip into place, test any chip location choice before final epoxy. My chip wouldn't work unless in specific positions. The alignment and position of the narrow end of the chip seem to be critical. Narrow end goes near the face as shown.

The sensing ring can be easily accessed by removing 2 ea. screws above the FB#1 and tipping the plastic housing down. A pair of needle nose pliers can then position and set the chip using Goop glue. Either side of the cable tombstone can be selected for the chip installation. Favor the chip being as close to the face of the ring as practical. Even if it is a bit proud, before hardening, the Goop glue will let the chip slide back a bit when the outer plastic housing cover is re-installed. Unlike epoxy, Goop glue allows easy re-positioning. Once cured it will tenaciously hold the chip into place.

Plastic handle OEM appearing un-programmed or non-chip brass keys are cheap to buy. I couldn't find a local locksmith to cut a steel key for me. I recommend choosing an OEM key look-a-like rather than a plain brass key. Then you will walk like a duck.
