How to Unlock Your Car Using A Cellphone When You Lost Your Keys
Unlocking your car with a mobile phone is possible as long as you have an extra key fob or alarm remote.
It requires the following items.
If you have lost your keys and you can call someone with a backup remote, simply have that person hold the key fob next to the phone and press the unlock button.
You may have to hold your cell phone near the car or even touching the car.
Once the person at the other end hits the unlock button while pointing the keyfob directly at (or touching) the cell phone, your car door should immediately unlock.
Try this and let me know if it works for your vehicle!
