Hear from Our Customers
Your key fob stops working at the worst possible moment. You’re standing in a parking lot, pressing buttons that do nothing, wondering if you’ll need to call a tow truck and spend your entire day at a dealership.
That’s exactly the situation we solve every day. When you choose McCausland Lock Service for your car key fob replacement in Thornbury, PA, you get your life back on schedule. We cut and program new key fobs for all major makes and models, often while you wait at our Prospect Park location.
No more wondering if your backup key will work when you need it most. No more paying dealership prices that can easily hit $400-600 for basic vehicles. Just reliable key fob service from a family that’s been solving these problems for over 100 years.
The McCausland family has been locksmithing since the late 1800s, and we’ve been serving Delaware County communities like Thornbury since 1981. Tom McCausland and his daughter Chrissy now run our Prospect Park shop, continuing the family tradition of solving the lock and key problems that matter most to local residents.
We’re the largest locksmith company serving the Delaware Valley area, but we still treat every customer like a neighbor. Whether you need a spare key fob programmed or you’re dealing with a complete key loss situation, we have the tools and expertise to handle any make and model on the road today.
The reason families in Thornbury trust us isn’t just our experience – it’s because we consistently deliver what we promise, when we promise it.
First, we identify your vehicle’s specific key fob type and programming requirements. Modern cars use different systems – some have basic remote functions, others have proximity sensors or push-to-start capabilities that require specialized equipment.
Next, we cut your new key fob to match your vehicle’s specifications. Our professional-grade cutting equipment ensures precise duplication, whether you’re working with a traditional transponder key or a more complex smart key system.
Finally, we program the new fob to communicate with your vehicle’s computer system. This involves connecting diagnostic equipment to your car’s onboard systems and syncing the new fob’s transponder chip with your vehicle’s security protocols. Most programming takes 15-20 minutes, and we test everything before you leave to ensure reliable operation.
You walk away with a fully functional key fob that works exactly like your original, often at a fraction of what you’d pay elsewhere.

Our car key fob replacement service covers everything from basic battery replacement to complete fob programming for total key loss situations. We work with all major vehicle manufacturers and can handle both older transponder systems and the latest proximity key technology.
In Thornbury and the broader Delaware County area, we see a lot of key fob issues related to Pennsylvania’s weather extremes. Cold winters can drain key fob batteries faster, while summer heat can damage the internal components. We stock replacement batteries and have the diagnostic tools to determine whether you need a simple battery swap or complete fob replacement.
For residents who commute into Philadelphia or work in the surrounding counties, having a reliable backup key fob isn’t just convenient – it’s essential. We can program multiple fobs for the same vehicle, so you’re never stuck without access to your car.
We also handle the more complex situations, like when you’ve lost all your keys or when your vehicle’s security system needs to be reset after a failed programming attempt.
You can typically save 40-60% compared to dealership pricing for car key fob replacement. While dealerships often charge $400-600 for basic vehicle key fobs (and significantly more for luxury brands), our pricing is designed to be competitive and transparent.
The exact cost depends on your vehicle’s make, model, and year, plus the type of key fob system it uses. Basic transponder key fobs cost less than proximity keys or smart keys that work with push-to-start systems. We provide upfront pricing so you know exactly what to expect before we start any work.
Yes, we can create and program new key fobs even in complete key loss situations. This process is more complex than duplicating an existing key, but we have the professional diagnostic equipment needed to communicate directly with your vehicle’s computer system.
For total key loss, we’ll need to verify your vehicle ownership through registration or title documents. Then we can generate new key codes, cut new keys, and program them to work with your specific vehicle. This typically takes longer than standard key duplication – usually 30-45 minutes – but you’ll leave with fully functional keys.
The process varies by vehicle manufacturer, with some requiring PIN codes or special procedures, but our experience with all major brands means we can handle these situations efficiently.
While our main location is in nearby Prospect Park where we can handle most key fob programming efficiently, we do provide mobile services for emergency situations or when you can’t get your vehicle to our shop.
Our mobile service is particularly helpful if you’re completely locked out or if your vehicle won’t start due to key fob issues. We carry portable programming equipment and can perform most key cutting and programming services at your location in Thornbury.
For routine key fob replacement or when you need multiple keys programmed, visiting our shop is often more efficient since we have our full range of equipment and key blanks readily available.
Key fob battery replacement typically takes just 2-3 minutes. We stock the most common key fob batteries and can usually replace them while you wait.
However, if your key fob still isn’t working after battery replacement, the issue might be with the internal circuitry or the programming connection to your vehicle. In these cases, you may need complete key fob replacement rather than just a battery swap.
We always test your key fob’s functionality after battery replacement to make sure all buttons work properly and the range is restored to normal operation.
We program key fobs for all major vehicle manufacturers, including domestic brands like Ford, Chevrolet, and Chrysler, as well as imports like Toyota, Honda, Nissan, BMW, Mercedes-Benz, and Audi. Our equipment works with both older transponder key systems and newer proximity key technology.
This includes traditional key fobs with separate keys, integrated remote head keys, and smart keys for push-to-start vehicles. We also work with commercial vehicles and trucks that use specialized key systems.
Each manufacturer uses different programming protocols, but our diagnostic equipment and experience allow us to handle the specific requirements for your vehicle’s make, model, and year.
In many cases, yes – especially if the damage is to the outer shell while the internal electronics remain intact. Key fob cases crack from being dropped or from general wear, but the transponder chip and circuit board inside often survive.
We can often transplant the working internal components into a new fob shell, which costs significantly less than complete key fob replacement and programming. This is particularly common with proximity key fobs where the expensive smart technology is housed in a replaceable case.
However, if the internal electronics are damaged – from water exposure, impact damage, or component failure – you’ll need complete key fob replacement and reprogramming. We’ll diagnose the issue and recommend the most cost-effective solution for your situation.
