Replace and program car key fobs and remotes. We aim to leave every Foster City job cleaner and more secure than we found it. If a lock can be saved, we save it; if it needs to be replaced, we tell you plainly and show you why.

When you need Key Fob Replacement in Foster City
Here are the key fob replacement scenarios we help Foster City customers with most often:
Many of these problems share a root cause — wear, misalignment, a worn key, or a security event like a move or lost key. Part of our job in Foster City is finding that cause so the fix holds instead of masking the symptom.
The sooner you reach out, the more options you usually have. A small issue caught early in Foster City is often a quick fix; the same issue ignored can turn into a lockout or a damaged door down the line.
- Fob is cracked or water-damaged
- Buttons or remote no longer respond
- Need a spare remote
- Fob battery replaced but still not working
How our Key Fob Replacement works in Foster City
Our key fob replacement process in Foster City is straightforward and transparent from the first call:
Match the fob: We identify the correct fob for your vehicle.
Program: We pair the fob to your car's system.
Cut the blade: We cut any emergency blade the fob uses.
Test functions: We confirm lock, unlock, trunk, and start.
If we discover something unexpected mid-job — a hidden alignment problem, a worn part, a vehicle quirk — we stop and explain it before proceeding. You always stay in control of the decision and the budget.
Throughout the visit we keep you in the loop. Before we touch anything on your Foster City property, you will know what we found, what we recommend, and what it will cost — so there are never surprises when the work is done.
What you get with Avant Guard Locksmith
Skill matters, but so does judgment. Knowing when to rekey instead of replace, when a lock can be repaired, or when a security upgrade is genuinely worth it saves Foster City customers money — and that judgment is what we bring to every visit.
We built Avant Guard Locksmith around the way people actually run into lock and key trouble — usually at an inconvenient time. That is why the mobile model matters so much in Foster City: it removes the friction of getting help exactly when you need it.
We would rather do the job right than do it twice. Taking a few extra minutes to align a door, clean a cylinder, or verify a key programs correctly is the difference between a fix that lasts and a callback — and our Foster City customers notice.
- Straight talk on options — we explain whether a repair, a rekey, or a replacement makes the most sense before we start.
- Local coverage — we serve Foster City and nearby communities like San Mateo, Belmont, and Redwood City, so help is rarely far away.
- Broad capability — one call covers residential, commercial, and automotive lock and key needs in Peninsula.
- Respect for your time — we aim to arrive when we say and finish efficiently without cutting corners.
- Care for your property — we favor non-destructive methods and protect doors, vehicles, and finishes while we work.
Key Fob Replacement: what to expect
For key fob replacement specifically, remote and smart fobs replaced and programmed. We aim to leave every Foster City job cleaner and more secure than we found it. If a lock can be saved, we save it; if it needs to be replaced, we tell you plainly and show you why.
Common benefits customers in Foster City mention include new fobs cut and programmed on site, remote, proximity, and smart key options, often costs less than the dealership, and battery and shell service too.
So what actually happens when we arrive? First, we confirm the problem in person, because what sounds like one issue over the phone can turn out to be another. Then we lay out your options for Foster City, agree on a plan and price, and get to work.
During key fob replacement, we protect the surrounding area — the door, the paint, the vehicle trim — and work methodically. When we finish, we test everything, hand over your keys, and make sure you know how to keep the hardware working smoothly.

What does key fob replacement cost in Foster City?
We do not publish one-size-fits-all prices for key fob replacement because every Foster City job is a little different — a simple rekey is not the same as an all-keys-lost programming or a high-security install. What we do promise is transparency: call us, describe the situation, and we will explain what drives the cost and what to expect.
Honest pricing starts with an honest assessment. For key fob replacement in Foster City, the final cost depends on factors like the type of lock or vehicle, the hardware involved, how many locks or keys are needed, and the complexity of the job. Rather than quote a misleading flat number online, we confirm the details and give you a clear price before we begin.
Beware of prices that look too good to be true. A rock-bottom quote in Foster City sometimes turns into a much larger bill on site. We prefer to be upfront: a fair, realistic price you agree to before we begin, with no bait and switch.

Reputation is everything for a local service business, and we treat every Foster City job as a chance to earn a customer for life. That means fair pricing, tidy work, and advice you can trust even when it means recommending the cheaper option.
