Final Word on Key FOB reprogramming
I need to know. I've read the threads- BUT...
How is it that so many eBay FOBs are sold with hundreds of 99% or better positive feedback?
The forums and local dealer say FOBs can not be reprogrammed.
What's the final word?

i would think majority are just replacing the shell , bcuz as far as i know you cant program another mb's key to work on yours ,
or they just buy them up to add to their keychain and perp like they got a benz ..

Well, you can "reprogram" a Merc SmartKey, but it requires that it be dissembled down to the pcb, the security PIC floated off, replaced with a new one, and a "virgin" flash dumped on it.
It's then basically a new, virgin key, and can be added via Star to any car. I can't imagine that it's a cost effective way to get a new key. I'm like the OP, suspect most are reusing the shells.

I like that Uk-C200, is there a write up on it anywhere? I've replaced soldered flash chips on ECU pcbs before. Not too bad. When you say PIC floated off are you talking about a standard and possibly readily available flash chip?

It's not super hard part to find - biggest problem is getting someone to sell you 1 as opposed to 1000 of 'em.
I'll see if I can dig up the info I had - was about a year ago, and if you've worked by hand with surface mount VLSI chips, it's the same sorta thing. I think the hard part was getting the code.
Shoot me a PM with your email address, I'll see what I can dig up.
EDITED for clarity : You will still need a setup to dump the code onto the key, or to program the PIC standalone.

eHow isn't so reliable though.
