Keyless Entry Problems?

you might wanna check for a possible short somewhere. or have someone check it. i have a gen 5 and i had EXACT same problem as you did. i took it to my buddy at work who could prolly build a toyota anything out of scraps. he found a short somewhere close to the fuse box actually, so it was temporarily messing with the locks as yours did and mine. he fixed it and now its fine.

I think if you use the manual key to lock the car it disables the smart key functions. Perhaps the battery may be dieing in your key as well?

You might have parked in a spot with a lot of Radio Frequency interference.

I have had that happen with other cars on occasion.

If it keeps happening I would get the system checked out

I agree. There is a radio station's transmitting tower near the local Toyota dealer here near our house. One tech there told me that when they have to program a new remote (any generation) they have to close all the doors in the shop and get right on top of the car's door lock. It could be 95 degrees in the middle of the Summer, but this is the only way they can do it. The range of all transmitters can really vary. The remote to our old 98 never worked anywhere near this same area. It's only 1-1/2 miles from our house. I would say within a 4 block area from this tower, the remote never worked.

I also agree with summerwind that you should still take it in to your dealer and get it on record, even if it works properly at the moment. That way you are covered if the problem continues, even out of warranty.
