should i be able to unlock anther ford explorer with my explorer key
Not normally but it does happen from time to time. Keys and locks are coded to work together. Usually vehicles with the same key codes are shipped to different parts of the country. I don't know about today but GM used to rotate the locks and keys in 4 year cycles beginning in 1968. In other words a '68 key blank will work in a '72, '76, '80, etc. Those keys had a letter code stamped on the shank that indicated which blank the key was. I was once able to unlock my '70 Pontiac with the ignition key for my '78 Cadillac. Both cars used the same key blank and the keys were cut close enough that it worked. HTH. -Jim
Dito JB. I could switch out the keys on my 58 Pontiac and 63 Olds with no problem. Only the door and ignition though. Back then there was a separate key for the trunk and glovebox.
More to your question concerning your 2003. It is possible two different keys will open the door, but I doubt they will start the vehicle. The key has a chip in it. Personally, I cut a non chip key for a hide-a-key and hid it under the vehicle in the event I locked the keys in the vehicle. It opens the door only.
Good points, OJ. I also have a non-chip spare for my '00 Grand Prix. As you said it'll open the door but won't start it. -Jim
