I removed the battery and close the doors of my car. Toyota Camry 2002. Now I want to put the new battery but am unable to open the car doors with key . Only rear part i.e. trunk accept the key i.e. I can open the trunk only. How can unfold back seats to crawl through the trunk

Have you tried your spare key? IF your vehile has z folding rear seat there should be a ...pull loop at the back of the seat. Pull on it and see what happens. Get back to us with results.

I can not open the doors neither on driver nor on the passenger side. Only I can open trunk with the key

Ok...look around in the trunk for a release for the rear seats.

Another idea. Do you see 2 little knobs sticking out of both rear seat backs.....near where you would put your head if you were sitting on...in....the back seat of the vehicle?

So....4757. Any good news about your car.....locked out....issue?

None of this is relevant as cannot accedes anything internal without breaking glass-no doors -no bonnet -no back seats as all are internal and locked out from such -even looked up charging battery from starter connections -up too high can't even see what wire is what.

Exactly the original question- there is no obvious access. not even the boot.
