Why won’t my Lexus key fob operate?
The battery dying is arguably the most frequent reason to reprogram a key fob. The fob will lose its previous programming when a battery is changed, which is unfortunate because it will make the vehicle inoperable. The good news is that it’s possible to reattach the fob using a sort of gimmick. It’s crucial to realize that this method only functions with a fob that has previously been attached to the vehicle before attempting it. Go to the next section if you have a new fob.

Now take the ignition key out. Put it in the driver’s door and use the key and buttons to simultaneously open and lock the door. For a total of three lock/unlock cycles, repeat this procedure.
Close the door after taking the key out. Try using the remote to unlock the doors. Open the door and start the car if that works. If it begins, your effort was successful. You might need to try it again, starting with the key in the ON position, if it doesn’t work the first time. (You don’t need to restart the computer in the car every time.) Before you make a successful connection, you might need to repeat the process a few times in some circumstances.

Why won’t my key fob open the door to 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.
