Any difference between fobs?

I bought a used key on Ebay recently and a locksmith programmed it with no problem. If you pull the key out of the fob, you can see 7 or 8 lines of numbers. I was able to find a key with all matching numbers except for the top line which I think is unique for each fob. At a minimum, the FCC number, the model number and the number of buttons needs to match.

If it were me, I would try to program all the fobs to both the cars.

I had not thought of that. Will run it by the wife and see what she thinks.

Had the new and old fobs and car reprogrammed at a local place. Twas a little more difficult than normal. Ended up costing $100.

Didn't do the MX-5 fob the same. They both have keys (for glove box, doors and trunk on the 3, and for ignition on the MX-5). Would have had to change the locks on all the stuff that took the key to have them the same.

The wife pinned both fobs inside my fanny pack to avoid dragging them out by mistake which apparently is what happened to my original fob for the 3.

I wear a fanny pack every time I go out. Both fobs just stay inside it. Have a spare 3rd key for the Tacoma in there, too.
