Frequently Asked Questions
Why won't my key fob work after replacing the battery?
If a new battery doesn't fix the issue, the fob may have lost its programming or the internal circuitry may be damaged. We can diagnose and replace the fob if needed.
Can you program a key fob I bought online?
Sometimes, but compatibility varies. Aftermarket fobs don't always work with all vehicles. Call us before purchasing to confirm compatibility.
Do you replace smart keys and push-to-start fobs?
Yes. We handle proximity smart keys and push-button start fobs in addition to traditional remote fobs for most makes and models.
How long does key fob programming take?
Most key fob programming jobs take 20–40 minutes depending on the vehicle and fob type.
What vehicles do you service for key fob replacement?
We service most domestic and foreign vehicles. Call us with your year, make, and model to confirm availability.
