So, new to me, 97 E300 D. Came with 2 keys, only 1 works. Can't find a lot of info about them, other than it's an infra red system as opposed to radio freqs (i think). Ignition key looks like a pretty standard, cut metal key. Flips out from the fob like a switchblade (sorta)
Is this remote (locks/unlocks doors) a dealer only item for replacement? Is replacement even possible?
Thanks
