Do all T-tops have a unique lock like your door or is it like the glovebox where any key will lock them?

I can't unlock mine.

I got replacement T-tops after mine were stolen along with all the hardware and weather stripping.

The dealership mounted them.

 

They all use exactly the same key used to open the doors, or trunk.

If they're different like you say, I'm sure they can be re-keyed, by a locksmith. The dealership should have told you what to do, or given you a key though.....I'd call them first.

 

My passenger one is probably not the original one nor am I the original owner, but I took it to a locksmith and they said they could rekey it to match the drivers side and the regular door key for $28.
