Published Date: Nov 25, 2025
Getting locked out is never fun, especially if you’re dealing with modern power door locks. Whether your key fob stops working, the car battery dies, or the keys are simply inside, knowing how to unlock a car door with power locks can help you avoid bigger issues. This guide walks through proven methods, what’s worth trying, and when to call Sure Lock & Key for trusted emergency locksmith services.
Method 1: Try Basic Built-In Unlock Options
Use Your Spare Key or Emergency Key
If you have a spare, use it to unlock the door manually. Many fobs contain a hidden mechanical key. Look for a small release switch and try it in the driver-side door slot.Unlock Car Doors with a Phone
If your car has an app-based system, you may be able to unlock a car door with a phone. Make sure your phone has a strong signal and your app is connected to the vehicle.Check for Hidden Key Slots
Some vehicles have hidden keyholes under door handle caps or embedded in the fob. These allow you to bypass the electronic system entirely.
Note: These methods are safest to try first. They’re low-risk and often work on newer vehicles. If these fail, don’t rush to force anything.
Method 2: Use Manual Entry Methods (With Caution)
Shoelace or String Loop Trick
Useful on older vehicles with vertical locks. Tie a loop, slide it into the top of the door, hook the lock, and pull up. It requires patience and practice.How to Unlock a Car Door with a Slim Jim
A slim jim slides between the window and weatherstrip to catch and lift the lock rod. It may work on some older models but can damage wiring, airbags, or lock systems in newer cars.Wedge and Rod Method
Insert a plastic wedge into the top of the door to create a gap. Then, guide a long tool or rod to press the unlock button. On some models, this may reveal a hidden car door unlock button.

Precaution: These methods can cause damage to the door frame, weather sealing, or internal electronics. Use only if you understand the risks.
Method 3: What To Do If Your Car Battery Is Dead
If your car won’t unlock and the key fob doesn’t respond, the problem might not be the lock — it could be a dead battery. In this case, remote access won’t work, and even smart-entry systems may fail completely. Still, you may be able to get in using hidden mechanical features most drivers forget about.
How to Unlock a Car with a Dead Battery and No Key
If the remote doesn’t respond, check your fob for a release switch that reveals a hidden manual key. This key often fits into a lock slot concealed behind a small cap on the driver’s side handle. Unlocking the door manually may restore access when electronics fail.
Note: If the door remains locked, the battery might need to be jumped. These solutions often work on smart-entry vehicles when the electronic system isn’t functional. If not, calling a professional may be the next step.
