How To Start The Car With Bypass The Car Alarm

Last Friday my car suddenly cannot be started moreover the car alarm also not working. It was very strange because the alarm still functioning few second ago. In the end I need to bypass the alarm to start my car.

I can’t figure out and solve this problem because I’ve tried many solution like jump start and plug/unplug the battery cable, so finally I have to call a wire-man to do it. After checking for some time he also can’t find out the problem but suspect the root cause is due to the car alarm has locked the car. The wire-man suggests me sending the car to the workshop to perform a full checking only will know the problem. But because the time already 10pm so the wire-man temporary bypass the alarm to start the car and let me drive home first.

I show you how the wire-man start my car with bypass the car alarm, this sharing is just for your knowledge and I do not encourage you to do it without any car repairing experience. Besides, different car type may have different relay so you should find out the correct relay only perform this action. This may help you if nobody can give you a hand in this situation at night.
