If you’re having trouble with your Viper alarm not locking or unlocking, you’re not alone. This can be frustrating and leave you feeling vulnerable.
In this article, we’ll explore some of the most common reasons why this might be happening and what you can do to fix it.
Weak battery
A weak battery can be a common reason for the Viper alarm not locking or unlocking. This happens because the battery provides the necessary power for the alarm system to function properly. If the battery is weak, the alarm may not function correctly.
Check the battery level in your remote control to make sure it is not low. You can also replace the batteries to ensure that they are fresh.
Also, check your vehicle’s 12v battery. Remember the alarm brain is connected to the vehicle’s 12v battery and Chasis Ground.
Broken remote
Sometimes, a broken remote can be the cause of the problem. If the remote is damaged, it may not be able to send the signal to the alarm system, causing it not to lock or unlock.
This can happen if the remote is dropped or exposed to water. If this is the case, you may need to replace the remote or get it repaired.
Malfunctioning door lock actuator
Another reason why your Viper alarm may not be locking or unlocking is because of a malfunctioning door lock actuator. The actuator is the mechanism that moves the door lock up and down.
If the actuator is not functioning properly, the alarm may not be able to lock or unlock the doors. You may need to replace the door lock actuator if it is not working correctly.
This actuator can be tested manually without the Viper remote. Testing it that way will help to eliminate the alarm remote or brain as the root cause.
Wiring issue
A wiring issue can also be the culprit behind your Viper alarm not locking or unlocking. The wiring can become loose or damaged over time, causing problems with the alarm system.
Check the wiring connections to make sure they are secure and not corroded. You may need to repair or replace any damaged wiring to get the alarm working properly again.
Common things to look for in these situations are loose butt connectors, crimp caps, T-Taps, and other plastic “Quick connect” types of tools used to tap into wires or create a connection:
The best way to make connections from 1 wire to another is with Solder:
Faulty alarm module
Finally, a faulty alarm module can also be the cause of the problem. The alarm module is the brain of the alarm system and controls all its functions.
If the module is not working correctly, it can cause issues with the locking and unlocking mechanism. In this case, you may need to replace the alarm module.
Tools you can use to fix Viper alarm issues:
- Multimeter: A multimeter can help you test the battery and wiring connections to see if they are working correctly.
- Screwdriver: A screwdriver is necessary for removing the remote control case and door panels to access the wiring and actuator.
- Replacement parts: If you need to replace the remote, door lock actuator, or alarm module, you’ll need to purchase the necessary replacement parts.
In conclusion, if your Viper alarm is not locking or unlocking, there could be several reasons why. By checking the battery level, inspecting the remote, testing the wiring and actuator, and replacing faulty components, you can get your alarm system working again. With the right tools and some troubleshooting, you can protect your vehicle and regain your peace of mind.
