Told to you up front.
- Key type: basic transponder is cheapest, remote head or flip key mid-range, proximity smart fob with push-button start the most
- Lost vs spare: an all-keys-lost call needs the key generated and the immobilizer paired from scratch, more labor than cutting a spare
- Drive distance across the metro, a downtown Congress garage is a shorter trip than a Lakeway marina or Dripping Springs
- Vehicle make and model, some European platforms need dealer tooling and a tow instead of on-site service

Recent car key replacement jobs in Austin
Car key replacement in Austin usually starts the same way. The keys went into a backpack at Zilker after a long Barton Springs afternoon, or into a beach bag at a Lake Travis boat ramp, or into a jacket pocket that got handed off in an ACL crowd, and now the car is sitting at the Domain or in ABIA long-term parking with no way in. Our mobile car key replacement dispatch is staffed 24/7, a technician drives to your vehicle with the cutting and programming gear in the van, and a new car key is cut and paired on site, no tow to a dealer. The local number is (512) 872-4378.
Lost car key, broken car key, or a spare cut on the spot
Whether you have a lost car key, a broken car key snapped off in the ignition, or you just want a spare cut before the next one goes missing, a mobile technician handles all three in your driveway or a parking lot. A worn or cracked blade can be re-cut by code or by decoding the door lock, a key snapped in the cylinder is extracted and replaced, and a spare is duplicated from your working key in minutes. If the car is locked with the keys inside, ask dispatch about a car lockout instead. If your car already has one working key and you only need a second fob or transponder key paired to it, that falls under our key programming service, not a replacement.
What a replacement car key means for your vehicle
Three categories cover almost every car on Austin roads. Older vehicles use a transponder key, a cut metal blade with a chip in the head that the ignition reads. Most cars from the last fifteen years use a remote head key or a flip key, same idea with buttons added. Late-model vehicles, common in the tech-corridor commute up MoPac and US-183, use a proximity smart fob with push-button start and no physical insert. The technician arrives with blank keys and fobs for the year, make, and model you give the dispatcher, cuts the blade by code or by decoding the lock, and pairs the new key to the car's immobilizer so it starts.
Make a car key with no key: all-keys-lost jobs
Making a car key with no key in hand is different from cutting a spare. On an all-keys-lost call the technician has to generate the key from the lock or from the VIN and then pair it from scratch, which takes longer and costs more. Most domestic and Asian makes, think the Nissan, Toyota, Honda, Ford, and Chevy trucks all over Central Texas, can be done on site in an ABIA lot or a Domain garage without a tow. Some European platforms, certain Mercedes, BMW, Audi, and Volvo years, plus a handful of newer push-button vehicles, are locked down to dealer tooling, and a tow to the franchise dealer is the honest answer. The dispatcher checks your year, make, and model before sending a technician so you never pay for a trip that cannot finish the job.
Replacement car key cost, and why it beats the dealer
Replacement car key cost is driven by three things: the type of key (basic transponder, remote head, or proximity smart fob), whether you still have a working key or it is an all-keys-lost call, and how far the technician is driving, since a downtown garage off Congress is a different trip than a marina off RM 620. Mobile service is almost always cheaper than a dealer once you factor in the tow the dealer requires and the days your car sits waiting on a mail-order fob. Pricing starts around $85 for a straightforward job, and the dispatcher quotes the full total with you on the phone before a technician is sent, so the figure is settled before any cutting begins.
Car key replacement across the Austin metro
Dispatch reaches the full Austin footprint. North along I-35 and US-183 into Round Rock, Pflugerville, Cedar Park, Leander, Georgetown, and Hutto. South along I-35 into Buda, Kyle, and San Marcos. West on RM 620, RM 2222, and SH-71 into the Hill Country and the Lake Travis communities, including Lakeway, Bee Cave, Lago Vista, Volente, and Spicewood, where lost-key calls at the boat ramps run heavy in summer. East along US-290 and SH-130 into Manor, Elgin, Bastrop, and Del Valle near the airport and the Tesla Gigafactory. A new car key cut and paired in a driveway in West Lake Hills or in a long-term lot at ABIA is the same job from the technician's side.
Car Key Replacement in Austin — common questions
What is the average cost to replace a car key in Austin?
Replacement car key cost in Austin starts around $85 and depends on three things. The type of key matters most: a basic transponder is the least expensive, a remote head or flip key is in the middle, and a proximity smart fob with push-button start is the most. Whether it is an all-keys-lost call or a spare cut from a working key changes the labor, and drive distance factors in since a Domain garage is a shorter trip than one out past Dripping Springs or Lago Vista. The dispatcher quotes the full price before a technician is dispatched.
How much should it cost to get a replacement car key versus the dealer?
A mobile replacement car key is almost always cheaper than the dealer once you add up the tow the dealer usually requires and the days your car sits waiting on a mail-order part. Simple transponder keys start around $85, while remote head keys and proximity smart fobs cost more because the blank and the labor are higher. You get an upfront total on the phone before anyone is sent, so there are no surprises when the technician arrives.
Can you make a car key with no key at all?
Yes, for most vehicles. On an all-keys-lost call the technician generates the key from the door lock or the VIN, cuts the blade, and pairs the new key to the car's immobilizer, right there at your location anywhere in the Austin metro. Most domestic and Asian makes are done on site without a tow. A small set of European platforms and certain late-model push-button vehicles are dealer-only, which the dispatcher confirms by year, make, and model before sending anyone.
Can a technician cut a new car key in the parking lot at Zilker or ABIA?
For most vehicles, yes. The technician drives to the Zilker, Barton Springs, or ABIA lot with blank keys, a cutting machine, and the gear needed to pair the new key in the van. The new blade is cut by code or by decoding the door lock, then the key is matched to your car so it starts. The whole job typically wraps up on site without a tow, usually in 15 to 45 minutes once the technician is on scene.
My car key broke off in the ignition. Can it be fixed on site?
Yes. A broken car key snapped in the ignition or door lock is extracted on site, and a fresh key is cut and matched to your car to replace it so you are not left with half a key and a stuck cylinder. Tell the dispatcher the year, make, and model and where the break happened so the technician arrives with the right blank and extraction tools.
Does this page cover replacing a lost or broken car key, and not other services?
Yes. This page is for replacing a lost car key, a broken car key, or cutting a fresh replacement car key, including all-keys-lost jobs where no key is left. If your keys are locked inside the car and you still have a working key, that is a separate car lockout visit. If your car already has one working key and you just want a second fob or transponder key paired to it, that is handled under key programming. If you are not sure which you need, the dispatcher will sort it out when you call.
How long does a replacement car key take once the technician arrives?
A spare cut from a working key is usually the quickest, while an all-keys-lost job runs longer because the key has to be generated and paired from scratch. Smart fobs with proximity systems take more time than basic transponders. Drive time is the other variable, since I-35 and MoPac back up during rush hours and Hill Country trips on RM 620 cover more distance. Most jobs finish 15 to 45 minutes after the technician is on site, and dispatch gives a live ETA when you call.
How much does a replacement car key or key fob cost in Austin?
Mobile car key and key-fob replacement in Austin starts at $85 — we cut and program the key on-site for most makes and models, usually well under dealer pricing. The exact cost depends on whether it's a basic key, a transponder key, or a smart/proximity fob.
Can I get a new car key without going to the dealership in Austin?
Yes — a mobile automotive locksmith can make and program most car keys and fobs on-site, with no dealership tow required. We come to you in Austin, cut the key, and program it to your car, usually in the same visit. (AutoZone and hardware stores can copy a basic metal key, but not program a transponder or fob — that needs a locksmith or dealer.)
Can AutoZone replace a key fob?
Only in a limited way. AutoZone sells blank fobs and shells and will cut a basic mechanical blade, but they do not program transponder or proximity keys — that needs a diagnostic tool plugged into the vehicle's immobiliser. So a fob bought there still has to be programmed by a locksmith or the dealer before it will start the car. If you already have a working key and want a spare, buying the blank there and having it programmed on-site is genuinely the cheapest route. If you have lost every key, the blank is no help — that is an all-keys-lost job, and in Austin it starts at $85.
Can I replace my car key myself?
Only partly, and only if you still have a working key. A spare blade can be cut cheaply, and on some models a second fob can be paired through an on-board procedure in the owner's manual — worth trying, and it costs nothing. What you cannot do at home is program a transponder or proximity key to a car that has no working key left: that needs a diagnostic tool talking to the immobiliser, and on many models a security PIN pulled from the VIN. Fobs bought online are also frequently locked to another vehicle or the wrong region and cannot be re-paired at all. In Austin, an all-keys-lost job on-site starts at $85.
Can AutoZone make a key without the original?
No. Cutting a key without an original means decoding the lock or pulling the key code from the VIN, then programming a chip to the immobiliser — none of which AutoZone does. That is an all-keys-lost job for an automotive locksmith or the dealer. A mobile technician in Austin can do it where the car is parked, starting at $85; the dealer route generally means towing the vehicle in and waiting on a parts order.
