I lost my whole set of keys last week. I made it home with the keys, so I figured they were in the house somewhere. I looked for hours to no avail. I think I must have thrown them away accidentally when I had a handful of trash that I took outside to our outdoor trash bin. Of course the next morning was trash day so by the time I realized my keys were lost, the trash had already been picked up. So I called the dealer to find out how much it would cost for a new key to be made for a 2010 Corolla. It was $260 for the key plus $120 to program it!! I looked on ebay and found a key for a little under $50, but I'd still have to pay to get it programed once it arrived (It came with the directions to program the door locks, trunk opener, and alarm sound, but it also needed special programming to start the car). I called around and found a locksmith that would program it for $60.00. The key arrived today, so I met up with a mobile locksmith who used his equipment to program it, but it didn't work. He said the key had the wrong chip in it. He said he sees that happen quite often with keys are not bought from a dealership (I my keys several years ago with my Ford Windstar and had no problem buying an aftermarket remote). So I had to pay him $250 for the key and the programming which at least was not as much as the dealership wanted. I'm so bummed! I guess I should be glad that I didn't have DH's truck key on my keychain. I hardly drive his truck so I keep that key somewhere else. I'm still out the $50 I paid on ebay and need to deal with getting a refund on that, too. Oh, and now that I bought the new key and replaced all of my other keys, I'll probably find the ones I lost. Anyone else have any nightmare lost keys expensive stories?
