Make one key for everything. Is this even possible? I would almost be willing to go back in time and bet who ever thought it would be a good idea to make door key different on older GM's. Anyone ever heard of someone re-keying the ignition to the same as the door?

If I remember correctly this has been discussed before and if you look at the 2 keys next to each other, the blanks are different so you can't use one key in the other slot. However, it might be possible to find a new door lock and ignition set that uses one key, I've seen sets being sold for different makes of cars, but never paid attention to number of keys. Problem is you'd have to find a set that also included a trunk cylinder if you wanted them all the same. Maybe a locksmith could "modify" the ignition using parts from a door cylinder so a door key would fit in it.

It might make more sense to install an alarm system with keyless entry and trunk opener. You would still have two keys but you wouldn't need to use the door key. Just keep it in case of battery failure.

The previous owner of my Fiero broke the driver's side lock, so we got a pair of locks from TFS. We were going to get them rekeyed so that they'd match the trunk, but the locksmith said it wasn't possible for some reason. Kinda sucks that I'll have three keys. Eventually after I install power locks I'll get keyless entry installed to go around that problem.

Some time during the Fiero's production run, the lock configuration (and associated key blank) was changed. You probably have newer door locks and an older trunk lock, or something to that effect.

Ihave one key for everything AND keyless entry. But I instaled the locks from newer GM to do it. NOT a bolt in setup but it can be done if you want it bad enough.

Basically you need to add a grove to one of the keys so it fits in the other lock (like groove the ignition key to fit in the door lock) and then have the other locks repinned to match the key that now fits.
