I went to replace the seal around my rear lights tonight and was disassembling the lights and reflector housing when lo and behold I noticed down in the channel that runs around the gas tank, an old, rusted Pebra key. Sure enough it worked when I tried it in the ignition. Must have been put there by a PO in the event keys were lost. I was about to get a replacement key cut, so it's as if the car has offered me yet another little gift. Gotta love it.
