Check the battery first If your remote key fob isn't working. This is the most frequent reason for your car not responding when you make commands.
If the issue persists it could be due to another issue. Luckily, most of these issues can be solved by following a few easy steps.
Check the Battery
Key fobs can perform a variety of functions, like remotely locking and unlocking your vehicle as well as turning on the interior lights and allowing you to start your engine with a push of the button. If you notice that your remote isn't responding the way it did in the past or requires you to move closer to your vehicle to allow it to lock or unlock the door, the battery in your remote might need to be replaced.
The majority of key fobs utilize the standard watch battery, usually the CR2032 coin cell. They can be found in a variety of hardware and grocery stores and even at some gas stations. The inside of the fobs can differ, so make sure to check the owner's manual to find out what kind of battery is required. It's also recommended to keep an extra battery in your bag as you never know when yours could get lost or break!
A remote key fob transmits a radio frequency signal (RF) to the vehicle's receiver. When you press the button on the key fob it transmits a specific signal that matches preprogrammed codes within the computer system of your vehicle. The vehicle's receiver is then able to verify the code and then opens or closes the doors based on the signal. If your key fob isn't working, it may need new batteries or the codes have to be reset.
In the meantime, while you wait for a replacement battery to arrive, you could try some things to make your device respond more effectively. For instance, most automobiles have a feature that allows you to turn off the key-chain alarm on your key fob by holding down the lock or panic button on your fob for 10 seconds, reports Consumer Reports. This is a simple trick that can prevent your key fob from being activated accidentally in public. It's also an excellent way to protect your vehicle and your home safe from unwanted burglaries.

Check the Buttons
