Hear from Our Customers
You’re not standing in a Wawa parking lot wondering if you’ll make it to work on time. You’re not arranging a tow truck from South Street or burning half your day in a dealership waiting room off Roosevelt Boulevard. You’ve got a working key fob in your hand, programmed to your car, and you’re already moving on with your day.
That’s what happens when you call a locksmith who actually understands the technology. Modern key fobs aren’t just remote controls—they’re tied to your car’s computer through transponder chips and encrypted signals. When they stop working, it’s rarely a simple fix you can Google your way through.
We handle key fob battery replacement when that’s all you need. We reprogram fobs that lost their pairing after a battery swap. We cut and program new transponder keys when you’ve lost your only one, and we do it right there at your car—whether you’re in Fishtown, University City, or anywhere across Philadelphia. No towing, no waiting for parts to arrive, no dealership markup that turns a $75 job into a $500 bill.
We’ve been solving lock problems in the Philadelphia area since the late 1800s. That’s not marketing language—it’s family history. Tom McCausland and his daughter Chrissy are the fourth generation running what’s now the largest locksmith operation in the Delaware Valley, working out of our Prospect Park storefront.
When car key fobs became standard in the early 2000s, we didn’t scramble to catch up. We already had the foundation—decades of understanding how security systems communicate, how to diagnose what’s actually broken versus what just needs a reset, and how to explain the fix without making you feel like you’re getting sold something you don’t need.
Philadelphia drivers from Delaware County to the city proper call us because we show up when we say we will, we quote honest prices before we start the work, and we use OEM parts so you’re not calling us again in three months when an aftermarket fob stops holding a charge.
You call and talk to someone who knows the difference between a dead battery and a deprogrammed fob. We ask what’s happening with your key—won’t unlock the doors, car won’t start, buttons don’t respond—and we give you a realistic price range right there on the phone. No “we’ll need to see it first” runaround.
Our mobile locksmith heads to wherever your car is in Philadelphia. Could be your driveway in Fishtown, a parking garage in Center City, or a grocery store lot in South Philly. We bring the equipment and the blank key fobs with us.
Once we’re there, we diagnose what’s actually wrong. Sometimes it’s just a CR2032 battery that costs five bucks. Sometimes the fob lost its programming and needs to be re-synced with your car’s computer. Sometimes you need a completely new key cut and programmed from scratch because you lost all your keys. We handle all of it on-site with the specialized programming tools that communicate directly with your vehicle’s security system.
The whole process typically takes 15 to 30 minutes for standard key fob programming. You watch it happen. When we’re done, your key fob works exactly like it did when the car was new—unlocking doors, popping the trunk, starting the engine. You pay the price we quoted, and you drive away.

When you need car key fob replacement in Philadelphia, PA, you’re paying for mobile service, on-site programming, and parts that actually last. You’re not paying for a dealership’s overhead, their multi-day wait times, or the tow truck you’d need to get your car to them.
We replace key fob batteries for every major vehicle make and model. We program transponder keys that use microchips to prevent your car from starting without the correct signal. We handle proximity fobs and smart keys that let you start your car without ever taking the fob out of your pocket. We work with basic remote entry fobs, flip keys, and laser-cut high-security keys. Whether you need key fob repair or complete replacement, we’ve got the equipment.
Philadelphia drivers deal with specific challenges that make mobile locksmith service essential. Street parking in neighborhoods like Manayunk or Northern Liberties means you can’t always get your car to a shop. Work schedules mean you can’t afford to lose a full day waiting at a dealership. Winter weather means standing outside your locked car on a February morning isn’t just inconvenient—it’s miserable.
We program key fobs for Honda, Toyota, Ford, Chevy, Nissan, Hyundai, Mazda, Dodge, Chrysler, Jeep, and most other makes. If your car was made after 2000 and uses any kind of electronic key, we’ve worked on it before. The programming equipment we use communicates directly with your specific vehicle’s year, make, and model, so the new fob integrates with your car’s security system exactly the way the factory intended.
Key fob replacement cost depends on what type of key your car uses and whether you need a completely new fob or just programming. Basic key fob programming typically runs $50 to $100. Transponder keys with embedded security chips cost $75 to $150. Smart keys and proximity fobs range from $200 to $400 depending on the vehicle.
Compare that to dealership pricing, which starts around $200 and can hit $600 for newer vehicles with advanced keyless systems. Dealerships charge more because they bundle programming fees with service charges and markup on parts. A mobile locksmith cuts out that overhead while delivering the same quality result.
If your key fob just needs a new battery, that’s a $10 fix you can often do yourself—most fobs use a CR2032 battery available at any pharmacy. But if the fob stopped working after you changed the battery, it likely needs reprogramming, and that’s where calling a locksmith makes sense. We come to you, diagnose the actual problem, and give you a firm price before we touch anything. No surprises, no bait-and-switch pricing that’s plagued parts of the locksmith industry.
Yes. Losing your only key is stressful, but it’s not the disaster it feels like in the moment. We can generate and program a new key from scratch using your vehicle’s VIN and our programming equipment. This is one of the most common calls we get from Philadelphia drivers.
The process is called key origination. We cut a new physical key blade based on your car’s lock code, then program the fob’s transponder chip to sync with your vehicle’s computer. This works for most cars made after 2000, though some European luxury models require additional steps that can increase the time and cost.
You’ll need proof of ownership—usually your registration and ID—because we’re creating a key that can start your car. That’s a security measure, not red tape. Once we verify ownership, we can typically have you back on the road within 30 to 45 minutes. It’s faster than arranging a tow to the dealership, cheaper than their pricing, and you don’t lose a full day of your life waiting in their service department. We’ve done this hundreds of times for drivers across Philadelphia and Delaware County.
Changing the battery can cause some key fobs to lose their programming. It doesn’t happen with every car, but it’s common enough that you shouldn’t assume you broke something. The fob just needs to be re-synced with your vehicle’s receiver.
Some cars let you reprogram the fob yourself using a sequence of steps—turn the ignition on and off a certain number of times, press specific buttons in order, that kind of thing. Your owner’s manual might have instructions. But many newer vehicles, especially those made after 2012, require a locksmith or dealership to reprogram the fob using specialized equipment that communicates with your car’s computer.
The other possibility is that the new battery isn’t seated correctly or the metal contact points inside the fob are dirty or corroded. Pop the fob open and make sure the battery is firmly in place and the contacts are clean. If that doesn’t fix it, the issue is likely programming, and we can handle that on-site without you needing to haul your car anywhere. This is a quick fix—usually 15 minutes—and way less expensive than replacing the entire fob.
Most key fob programming jobs take 15 to 30 minutes once we’re at your location. That includes diagnosing the problem, cutting a new key if needed, programming the fob to sync with your car’s computer, and testing it to make sure everything works—unlocking, locking, trunk release, remote start if your vehicle has it.
If you’ve lost all your keys and we need to originate a completely new key from scratch, it might take closer to 45 minutes. More complex vehicles with advanced security systems—certain luxury brands or newer models with proximity sensing and push-button start—can take a bit longer because the programming process involves more steps to ensure the transponder chip communicates properly with your vehicle.
Response time to get to your location in Philadelphia is typically 20 to 30 minutes, depending on traffic and where you are in the city. We run mobile service, so we’re not asking you to bring your car to us or wait days for an appointment. We come to your driveway, your workplace parking lot, the street where you’re parked—wherever your car is sitting.
We program key fobs for nearly every major vehicle manufacturer—Honda, Toyota, Ford, Chevy, Nissan, Hyundai, Mazda, Dodge, Chrysler, Jeep, Kia, Subaru, Volkswagen, and most others. If your car was built after 2000 and uses an electronic key fob, we’ve likely worked on that exact model before.
The programming equipment we use is updated regularly to work with newer vehicle security systems. We carry blank key fobs for the most common makes and models, and we can usually source less common ones quickly if needed. We’ve programmed everything from basic Honda Civics to newer Ford F-150s with smart key systems.
There are occasional exceptions—some European luxury vehicles or very new models with proprietary systems that only the dealership can access. But that’s rare. For the vast majority of cars on Philadelphia roads, we can cut and program a working key fob on-site the same day you call. If we can’t handle your specific vehicle, we’ll tell you that upfront rather than waste your time.
The main differences are cost, convenience, and time. Dealerships charge $200 to $600 for key fob replacement and programming. Locksmiths typically charge $50 to $200 for the same work. That’s not a small gap—you’re often paying two or three times more at the dealership for the identical result.
Dealerships require you to bring the car to them, which means arranging a tow if you’re locked out or can’t start the vehicle. They also work on appointment schedules, so you might wait days to get in, especially during busy weeks. A mobile locksmith comes to wherever your car is and handles it the same day, usually within an hour of your call.
The quality of the work is the same. We use OEM-quality parts and the same type of programming equipment dealerships use to sync the key fob with your car’s computer. Your new key fob will work exactly like the original—same range, same functions, same reliability. The difference is we’re not marking up the price to cover a service department’s overhead, and we’re not making you rearrange your entire week to accommodate their schedule. For Philadelphia drivers juggling work, family, and the chaos of city parking, that convenience matters.
