Expert Answer

The time required to install a car alarm on a vehicle that doesn't already have one can vary, typically ranging from three to six hours, depending on skills and proficiency. The complexity of the installation process depends on the type of car alarm and its features. Some cars may be pre-wired, simplifying the electrical aspect of the installation. Basic car alarms, with features like door or window sensors, may take fewer hours, while more comprehensive systems with shock sensors, proximity sensors, and additional complexity could extend the installation time. In certain cases, especially with intricate electrical work and numerous sensors, the installation might surpass the six- to eight-hour mark.

Question

How can I disable my alarm?

Community Answer

Unhook wires going to the battery. If that's not an option go to the control box, usually under the dash, and cut the red and black wires going in.

Question

Will it be possible for a new key to be programmed for a car alarm without necessarily going through the installation process from the beginning?

Community Answer

It depends on the car. You can take your car to the dealer and they can reprogram the key for you. It will cost a bit of money, but it would be the best thing to do if you want it done correctly.

Question

What do I do if my car alarm fob isn't working and my car alarm is going off?

Community Answer

Likely the wire is shorted. Verify if there are shorted wires: use a multimeter. Reconnect the wires if you're confident or have the mechanic fix it.

Question

Can I connect a car alarm to a battery separate from the main car battery?

Community Answer

Theoretically you can wire it to any 12v power source, such as a secondary battery.
