Key Replacement - Save vs Dealer in Ventura County

2002 Toyota 4runner Remote Replacement - Fast, Affordable & Professional

I got a call from a woman up in Mission Canyon, one of those winding-road neighborhoods where the houses sit back in the oak trees above Santa Barbara. Her 2002 4Runner had been sitting in the driveway for a week. She had the key, the car started fine, but the fob had stopped working entirely. She'd already swapped the battery herself. Twice.

When I pulled up, she handed me the fob and walked me through what she'd tried. Fresh CR2032, still nothing. No response on any of the four buttons. I popped the case open right there on the hood. The battery contacts had a thin film of corrosion on them, the kind you don't always catch in bad light, and the internal contacts were slightly bent inward from what looked like a few hard drops over the years.

I cleaned the contacts, gently reset the bend, and seated a new CR2032 the right way. Walked back about thirty feet toward the treeline. Locked the doors. Unlocked them. Tested every button. All four working, range solid.

She watched the whole thing from the front steps and said she'd assumed she needed a whole new fob. She didn't. Just the right small fix, done on site, for a fraction of what a dealer visit would have cost her even before they touched anything.
