Replacement Key
I have a 1999 E430 and I need a replacement ignition key? I've searched high and low on the internet and trying to avoid the high cost from a dealer, any suggestions?

Try calling around to see what the dealer charges for the key. They may also try to add on "programming" in addition to the key but in nearly all instances, it's simply inserting the Smartkey into the ignition and letting the two units interrogate, handshake and synchronize their brains....like Spock and the mind meld trick. So you MAY want to read up on this and see if you can save yourself $50+ and stick it to the dealer by sticking it in yourself.
On average the dealer may charge $250-400 for the Smartkey and about $100 for the matching metal blade key. Call around to any MB dealer nearby which you're willing to drive to as the price is set by independent dealers themselves. SHOP AROUND.
A few years back, I checked the cost to the dealer and it was more like $75 and $10....(sigh)
I sat there while he did it (30 min) and he let me test every function repeatedly to make sure it worked. The old one still works. I've had and used it exclusively for 5 months without issue. This was in Atlanta area -- hopefully you can find one in your area. Worth shopping around in there if the MB dealer is trying to get too much.

overseas creative minds having bypassed and learned how to program Smartkeys have been shared for a few years now.

Recall is was ~$180 for FOB and programming (My rig is a 1999 E320). He's located just outside Atlanta. Super guy and I'm sure he'll guarantee his work.
