Quick answers for Walnut

Is it cheaper to replace the fob battery or the whole fob in Walnut? +

If the buttons work and it just went dead, a battery is a few dollars. Replace the fob when it is water-damaged, cracked, or lost — then it needs programming to your car.

Can I use an aftermarket fob instead of OEM in Walnut? +

Sometimes. Aftermarket fobs cost less and work on many models, but not all. Give the year and make so the locksmith can say what actually programs to your car.

Do I have to tow the car to get a new fob in Walnut? +

Usually no. Fob programming is typically done on site where the car is parked, as long as it is somewhere safe to work.

What should I tell the locksmith in Walnut? +

Cross streets, gate or intercom codes, parking rules, and car vs home. For vehicles, include color, make, and where it is parked. ZIP 91789 is commonly routed from Walnut.
