What to Do When Keyless Entry Fails?

[IsabelaMarie]

Usually, when the key fob fails and you can't open the car door, there are two possibilities: first, the car's battery is dead, or second, the key fob's battery is dead. In such cases, regardless of subsequent troubleshooting or repairs, the first step is to use the spare mechanical key to open the car door. Here are the methods to open the car door: 1. Conventional folding key: Generally, there are two types of keys with keyless entry functions: conventional folding mechanical keys and hidden mechanical keys. If it's a conventional folding key, you can directly use the mechanical key to open the door when the battery is dead. 2. Hidden mechanical key: Usually, the spare mechanical key is hidden inside the main key. It's not visible under normal circumstances, but when needed, you can pull it out and use it as a regular mechanical key to open the car door. The mechanical key typically only unlocks the driver's side door, while other doors need to be opened manually from inside the car.
