Transponder Key Programming in Dallas–Fort Worth
If your car key has a chip in the head and you turn it to start, that’s a transponder key. A copy won’t start the engine until the chip is programmed to your car — and that’s exactly what we do, on site.
Most cars built in the last couple of decades use a transponder key — a traditional key with a small chip embedded in the plastic head. When you turn the key, the car checks that chip against its immobilizer before it lets the engine start. It’s a great anti-theft feature, and it’s also why a plain hardware-store copy cranks but won’t start.
We cut the key and program the transponder chip to your car’s immobilizer on site, so your copy or replacement actually starts the engine — not just turns in the lock.
Why a transponder key needs programming
A transponder key has to satisfy two separate checks in your car:
- The mechanical cut — the blade has to match your lock to turn.
- The chip code — the transponder has to be programmed to your immobilizer or the engine won’t start.
- Both are required — a key that’s only cut will turn but not start, which is the classic ‘my copy won’t work’ problem.
- Done at your car — the programming has to communicate with your vehicle.

Common questions
Why won’t my copied key start the car?
Because only the physical cut was copied, not the chip. Transponder keys have a chip that must be programmed to your car’s immobilizer. Without that step the key will turn in the ignition but the engine won’t start — we do the programming that fixes it.
How do I know if I have a transponder key?
If your key has a thick plastic head (often with no buttons, or with a separate fob) and the car built in roughly the last 20 years, it almost certainly has a transponder chip. Send us your year, make, and model and we’ll confirm.
How much does transponder key programming cost?
It starts at $350 and depends on your vehicle and key type. We confirm the price when you book.

What our customers say
Real Google reviews from LockNCal customers.
The website was easy to navigate and I found the service I needed and was able to book the perfect time between work. The technician messaged me a day early letting me know that he would be in the area and gave me the option to get it taken care of early but unfortunately I was working. If I hadn't been that would have been amazing to get it done ahead of time. He was on time and very pleasant. Worked quickly and got my problem taken care of. It was such a better experience than sitting in a waiting room with strangers or having to take an Uber back and forth to avoid such situation. I'm already recommending them to my friends because of how easy it was. Why go to a shop to get your car fixed at the shop can just come to you?
This is my first mobile mechanic experience and I have to say Jose made it the best. He was early on the appointment he was very professional very knowledgeable and polite. If you need a mobile mechanic call lockncal and try to get Jose out he'll fix you right up. I have to admit that I was a little skeptical about paying up front because I've never used this type of service before but the end result I am very pleased and will use this service again thank you Jose again if I need anything else I'll get you out to fix it.
Jose contacted me swiftly after I filled out the form on the website and discussed the part needed (clock spring) and the appointment time. I was able to get in within 2 days. He arrived early and got right to work and was done rather quickly. He communicated well the whole time. I’m very glad to be back on the road and know my airbag light is off and all my steering wheel buttons work again!
On time, reliable and incredible service. Very honest about our repair and showed us the code log. Highly recommend. Already shared his information with a family member who didn’t even know this kind of service exists. Now I can feel confident that our family’s vehicle is safe to drive again.
This is a great company to deal with ,my cruise control stopped working & they came out & gave a free diagnosis which gave a clear picture of what was exactly wrong ,highly recommended ,very professional & honest,thank you again !!!
I initially went to the dealership when the airbag light in my Nissan Rogue had come on. Upon diagnostic review, the dealership advised that it would cost around $4500 to correct the issues that they were seeing with the system. I decided to get a 2nd opinion and I called DFW Safety Restore. Jose was able to work me in next day. He was prompt and right on time for my appointment in coming out to my house to run a diagnostic on my car. The first scan showed a host of issues, the same issues the dealership reported and more. So many, that Jose suggested resetting the codes and rerunning the diagnostic to get a true picture of what was going on. He said if there are true issues with the system the diagnostic codes would reappear. The reset worked and the system went back to normal. I am so thankful for Jose, and DFW Safety Restore for saving me from unnecessary and very expensive work on my car. If you have airbag system issues with your vehicle, I highly, HIGHLY, recommend you give DFW Safety Restore a call first.
