It’s more likely that you will be allowed to utilize an aftermarket key fob if your automobile is at least ten years old, according to CR’s Ibbotson. Many of these less sophisticated fobs can be configured by the consumer, a local technician, or an automotive locksmith.
Ibbotson advises making sure to phone your neighborhood garage first to confirm that they can do the task, as key-fob programming equipment levels can vary from shop to shop. For instance, a Maryland-based repair shop called Murray’s Auto Clinics informed CR that they are unable to program key fobs for any vehicle with push-button start or keyless entry.
We took our vehicle to M.J. Sullivan Hyundai in New London, Connecticut, where we were charged $120 for programming (one hour of labor), which is what they would have charged us if we had purchased the key fob from them.
Hyundai sent us a laser-cut mechanical backup key for $72.47, bringing the total cost to $272.42 (the car waited at the shop for two days); if we had ordered the key fob through the store, the total would have been $428.92).
For some makes and models, you can purchase a cheap aftermarket fob and program it yourself if your home unexpectedly gains a third driver, such as a teenager.
We purchased a fob from BestKeys from Amazon for CR’s 2008 Chrysler Town & Country minivan. Although it lacks the Chrysler branding on the back, it resembles the two original fobs that came with the minivan when it was new. The uncut mechanical key and internal circuitry were both included in the $14.30 price. (However, we didn’t see the need to shell out the cash to have a locksmith cut that third key.)
Chrysler customers can program a third key fob themselves if they already have two functional ones, just like GM owners can. The owner’s manual contains clear and straightforward programming instructions.

The key fob won’t be recognized by your car because the remote’s battery is dead. The actual remote is damaged or is no longer programmed to your vehicle. Low automobile battery voltage. The keyless entry system is broken.
Why won’t my key fob open my car?
It can be quite aggravating and even hazardous if your key fob won’t open the door to your car, especially if you have a young child or pet locked inside. Here are a few explanations for why your smart or remote key fob isn’t opening the door, along with solutions.
Any of the following could be the source of your issue if nothing happens when you push the unlock button on your remote control or key fob:
Your remote control or smart key fob’s battery is either dead or too low to maintain a strong signal. Replace the battery by opening the fob.
Your vehicle’s receiver(s) for the keyless entry system may not be receiving the signal from the key fob. When pressing the unlock button, try holding the fob close to the door handle. If it opens the door, there might be an issue with the key fob’s battery, the keyless entry antenna, or the wiring.
The unlock button on the key fob itself can be problematic. Try the panic, trunk release, and lock buttons. If the other buttons function properly, a faulty unlock button is the issue. You’ll require a fresh key fob (which will have to be programmed to your vehicle). The fob may be damaged, the keyless entry antenna, or the wiring may be at fault if none of the other buttons function after you have tried a new battery in the fob.
Your key fob’s entry code is missing. Every time you use the key fob to unlock or start your car, the rolling code that many automobiles employ changes. It can be necessary to have the fob reprogrammed by a car dealer if a communication error has corrupted the coding inside.
The electric door locks might be broken. The power door locks could not be able to unlock due to a problem with the wiring or control circuitry or even a blown fuse. To find the defect, the electrical system will need to be further diagnosed.
Your car’s battery is nearly dead or very low. Before the power doors may unlock, the car battery may need to be changed or given a jump start. Of course, you won’t be able to open the hood until you find another way to enter the car.
