I have 2007 toyota camry hybrid bought from a auction with no keys. Locksmith came to make and program a key but claim 12v battery was to low charged so I boosted battery for a hour with Booster pack
Allegedly programming key VSC displayed on dash and car wouldn't crank at all,
not sure if key was recognized because dashboard went black with all
accessory power. I took to get 12v battery charged, they said it is a good battery
13.2v. I put 12v battery back in car still no accessories, but have horn, interior
lights, brake light & parking lights which was condition before having key
programmed
