Why Jeep Wrangler’s Alarm Keep Going Off – Solutions
As the causes could be simple to fix, try those before going to the experts.
Damaged Battery
Throughout the years, car alarms have developed in sophistication. Nowadays, the systems can be proactive to alert us to potential problems with any car.
The alarm system might be activated, for instance, if your jeep’s battery is on its way out, alerting you to the problem. Following the problem, you could take action to change the battery.
Your alarm might sound like a warning if you try to start your car with a dead or malfunctioning battery.
Check the water levels and battery age. If the main battery is more than two or three years old, you might need to replace it.
Key System/Remote Fault
After a while, the key remote for your Jeep Wrangler may stop working properly. Signal degradation, advancing age, or a drained battery could all be the reasons for this.
Additionally, they frequently experience a signal loss, which fails and calls for reprogramming. They have tiny batteries, and all electrical devices have a lifespan limit.
If there is a signal outage, pressing the unlock button can cause your alarm to go off. Resetting the key Fob is an easy process that doesn’t require special knowledge or equipment.
To start, all you need to know is how to reprogramme, and you are good to go. You’ll save some cash using this DIY method that would have otherwise gone to the mechanic.
Try out the following process to fix the key remote/Fob:
- First, change the battery of your jeep’s key remote
- Close all of the jeep’s doors completely when seated inside
- Your foot should be on the brake pedal
- Turn on the ignition with the key
- Set the switch to “ON” and wait for a few seconds
- About three seconds will pass while the security light is on.
- The moment the light turns ON, the key system should be reset.
Poor BCM (Body Control Module)
The BCM component or module supervises and manages several electronic systems attached to the jeep’s body. Your alarm will sound periodically and send inaccurate signals due to a defective BCM.
BCM controls the following modules:
- Door Locks
- Automatic Headlights
- Alarm system
- Windows
Key Fob/Remote Buttons Jam
For whatever reason, a defective key fob will cause the alarm system to receive false signals.
Signals will be disrupted, and your alarm may go off if a key fob button is stuck. Additionally, it will quickly deplete the battery in your key Fob.
If this occurs, the alarm will be off on your car, which can cause unintentional sound.
Common causes of key fob damage include some of the following:
- Buttons becoming stuck
- Becoming frequently dropped
- Frequent moisture jam to the keys
- Inadequate key fob battery
Damaged Sensor
A sensor could malfunction if your jeep is frequently exposed to mud, grime, and water. For instance, the hood latching sensor malfunctions when it gathers dust from off-road driving.
It may convey the wrong message and result in a false alarm. A hood sensor is a hijack protection device that is made to identify unauthorized hood openings.
Spoiled Wire Connection
A damaged cable or corrupted connections might send the wrong signals, causing short circuits and chaos with your car’s alarm system.
Since it’s difficult to reproduce any electrical glitches, you’ll need to thoroughly inspect all door latches.
And connections or take the vehicle to any mechanic to figure out where the issue is.
Door Pins/Connection Problem
If you frequently take your Jeep doors off and on, you should carefully check every connection to ensure they are not broken.
Verify that all of your door pins are connected properly. Disconnecting the electrical systems of the doors is one method of isolating them.
If the problem disappears, you will know that any of your doors have a wiring issue.
Red Button Pressing
Unintentionally pressing the key, Fob’s red panic button immediately activates the alarm and starts beeping. This safeguard prevents hijacking.
To stop it, press it again or try other activities like starting your engine to check if the problem solves.
