Here's how you'll likely unlock your Jeep Liberty's doors with the engine off:
* Using the key fob: This is the most common method. Press the unlock button on your remote key fob. This will unlock all the doors.
* Using the key in the driver's side door: Insert the key into the driver's side door lock and turn it to unlock. This unlocks only the driver's side door on most models; you will then have to manually unlock the other doors from the inside. Some models may unlock all doors this way, but it's not typical for the Liberty.
* Manually unlocking the doors from the inside: If the car is unlocked, the inside handles should unlock the doors.
If none of these methods are working, you might have a problem with your car's electrical system, your key fob battery, or a problem with the locks themselves. Consider checking the key fob battery or seeking help from a Jeep mechanic.
