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
