Push to start key programming in Dallas, done at your car.
Key not detected, a lost smart key, or you just want a spare. We program proximity keys through the OBD port wherever the car is parked.
First we check whether a fresh battery or the backup start spot fixes it. If it doesn't, we bring the right key and program it on site.

How a push-to-start smart key talks to your car.
A smart key never goes in the ignition. The car finds it by radio, checks it, and only then lets the start button work.
Antennas inside the car, in places like the door handles and the cabin, send out a short-range, low-frequency wake-up signal. When your fob is close enough to hear it, it wakes up and answers over a radio link with its coded ID. If the car recognizes that ID, the door unlocks when you touch the handle, and when you press the start button with your foot on the brake, the immobilizer lets the engine run.
That is why a proximity key has to be programmed to the car. A new fob, even the correct part number, carries an ID your car has never seen. Programming adds it to the car's list of authorized keys. On most vehicles we do that through the OBD-II diagnostic port under the dashboard.
The security chip inside works on the same idea as a regular chipped key. Read what a transponder key is.

The backup pathMany smart keys can still be read at very close range with a dead battery. On many models, holding the fob against the start button, or in a marked spot in the console, lets the car start. Your owner's manual shows the spot for your car.
Key not detected? What usually causes it.
That message means the car sent its wake-up signal and didn't get an answer it trusts.
Before anyone orders a new smart key, rule out the simple causes. Almost every push-to-start fob runs on a small coin cell battery. As it weakens, the fob's answer gets weaker, and the car stops finding it reliably, sometimes only from certain spots in the cabin.
A fob that was dropped, crushed or got wet can fail the same way even with a new battery, because the board or its antenna inside the case is damaged.
Quick test: on models that support it, hold the fob right against the start button and press the button with your foot on the brake. If the car starts that way, the key is still registered to the car and the battery is the likely problem.
Weak coin battery
The most common cause. The fob may still unlock up close, but the car loses it from the seat. A fresh battery of the correct type usually fixes it in a minute.
Damaged or failed fob
New battery, still not detected. The board or internal antenna has failed. That fob gets replaced, and the new one programmed to the car.
Every smart key lost
Nothing left to copy from. A new key is programmed through the OBD port, which on some vehicles adds security steps and takes longer than adding a spare.
The emergency blade gets you in.
Most smart keys hide a metal key inside the case, released by a small button or slide. It opens the driver's door even when the fob is dead. On many cars the keyhole sits behind a small cap on the door handle.The fob-to-button backup gets you started.
If the backup spot starts the car, you have time to buy a battery. If it doesn't, the fob itself or its programming is the problem, and that is a job for us.
Aftermarket or OEM smart key, and when the dealer is the honest answer.
Not every smart key that looks right will talk to your car.
An OEM key is the manufacturer's own part, the same unit a dealer sells. An aftermarket key is built by a third party to work with your car's system. Both get programmed the same way, through the OBD port.
Good aftermarket smart keys work on many vehicles and cost less. Quality varies, though, and range, button feel and battery life are not always equal to the original. We match the key to your exact vehicle before ordering and tell you which options fit.
Thinking of buying a used smart key online? Some are locked to the car they came from and cannot be programmed to a second vehicle. Call with the part number before you buy.
A small number of high-security luxury and European vehicles require OEM-only programming that only a franchised dealership can perform. If your vehicle falls into that category, the dispatcher will tell you on the call rather than send a technician who cannot complete the job.

How smart key programming works at your car.
Three steps, in order, every time.

Open- Step 1
Identify the system and the key
We start with year, make and model, then confirm the exact smart key your car takes, usually from the part number or FCC ID printed on the original fob. If a fresh battery or the backup start spot solves the problem, we tell you that first.
- Step 2
Program over the OBD port
Our programming equipment plugs into the OBD-II port under the dashboard and adds the new key to the car's list of authorized keys. Some vehicles need a security access step or a waiting period before they accept a new key. The emergency blade is cut to your locks during the same visit.
- Step 3
Test every function
We walk the car with the new key: passive unlock at the handles, push to start with the key in a pocket, every remote button, the blade in the door lock and the backup start spot. Then we check that your other keys still work.

Push-to-start key questions we hear most.
How much does push to start key programming in Dallas cost?
Our cost guide lists push-to-start smart key replacement at $200 to $400 and up. The final price depends on the vehicle, whether you choose an OEM or aftermarket key, and whether you still have a working key. We quote the key and the programming before anyone is dispatched.
My car says key not detected. Do I need a new smart key?
Not always. Start with a new coin battery of the correct type. On many models you can also hold the fob against the start button, or place it in a marked spot in the console, and press the button to start. If that works, the key is still registered to the car. If a fresh battery and the backup spot both fail, the fob is likely damaged, and we can test it at the car.
Can you program a push-to-start key if I lost all of mine?
Yes, on most vehicles. With no working key left, the new key is programmed through the OBD port, which can involve extra security steps and takes longer than adding a spare. A small number of high-security luxury vehicles require OEM-only programming that only a franchised dealership can perform, and the dispatcher will tell you that on the call.
Is an aftermarket smart key as good as an OEM one?
It depends on the vehicle and the key. Good aftermarket smart keys work on many cars and cost less, but quality varies and range or battery life may not match the original. An OEM key is the manufacturer's own part. We tell you which options fit your exact vehicle before ordering.
How do I get into my car if the smart key battery is dead?
Use the emergency blade. Most smart keys hide a metal key inside the case, released by a small button or slide. It opens the driver's door lock. On many cars the keyhole is behind a small cap on the door handle, which comes off to expose it.
Do I need to bring all my keys to the appointment?
Yes, have every key you want to keep using. On some vehicles the programming session registers all keys at once, and a key that is not present can stop working afterward. If a key was lost or stolen, ask us to remove it from the car's memory during the same visit.
