2007 Prius, lost both keyless fob's. I have a spare key from another Prius. I would like to (if possible) reset, without the master key. Is there anyway to set another keyless fob to another Prius. Same year. I've read lots of threads of resetting keyless fobs, and lots of "recipe's" on how to do so. Does anyone have known, good info on how to do this correctly?
You need to take the car to a dealer or locksmith with the proper equipment. The dealer/locksmith can do immobilizer and smart key resets. This will delete all the old keys, and allow registration of new (and even used) keyfobs. Getting the car to the dealer is part of the problem. The car is in Park, and there's no way to get it out of Park without a key... You'll probably want a flat bed truck, and dollies under the front wheels. Negotiate prices before this sort of job. At least an hour of tech time, plus the replacement fobs.
