How to Remotely Open a Car With a Cell Phone

Forgetting your car keys inside the vehicle can be stressful and take a hit on your wallet if you end up needing a locksmith to open the door. If you have a spare key remote opener and someone else can access it, you can use your cell phone's speaker to remotely open your car's door; however, this won't work with average RKE (remote keyless entry) openers because the signal they transmit is not the same as the signal cell phones transmit. Ultimately, trying with your specific RKE opener will determine if you can accomplish this with your car.


Instructions
Things You'll Need:

* Spare key remote opener

1.Call the person that has access to your spare car remote opener using your cell phone.

2. Set your phone to "Speaker" mode by pressing or tapping the "Speaker option."

3. Ask the person to place the spare car remote opener close to the phone's speaker.

4. Place your phone beside your car's door handle with the speaker facing your door. Ask the person with the spare car door opener to press the "Open" button while having it as close as possible to the phone's speaker. The car will then be unlocked. You may have to try to place your cell phone in different areas of your car's door handle before it opens your door remotely because the receiver's location varies depending on the type of car. The key opener should be less than a foot from the car's door handle.
