Why Won’t My Lights Flash When I Lock My Car?

If you’re having trouble with your lights flashing when you lock your car, there are a few things you can check. Make sure that the lights are installed properly. If they’re not, the wires may be loose or disconnected. You can also check to see if the fuse is blown this will prevent any current from getting through.

If that doesn’t fix the issue, try cleaning out any dust or debris from around the light housing and try again. This will help ensure that no dirt or dust is preventing them from working properly. If that doesn’t work either, it might be time to bring in a professional.

The way the system works

The way the system works is that there are two separate parts. The first part is the actual locking mechanism. This is something that you can control with your key fob or manually with a switch inside the car. The second part is the flashing lights, which are controlled by an entirely different mechanism. In order to get your lights to flash when you lock your car, make sure that you’re using both mechanisms correctly.

What can cause this issue?

One of the most common reasons your lights won’t flash when you lock your car is that the battery just needs to be replaced. If your key fob isn’t working, it could be because of a dead battery. If the car is still running properly when you try to lock it, but the lights don’t flash, then it’s likely that you need a new battery.

Another thing that can cause this issue is a faulty light switch in your car. If you’re having trouble locking and unlocking your car, or if your lights won’t flash when you lock the doors, then this may be an issue.

What can you do to fix it?

Check your fuses. Fuses blow out all the time for no reason, so check your fuses first. If one of them is blown, replace it and see if that fixes your problem.

Replace your bulbs. Your lights might be burned out or broken, which is why they aren’t flashing when you lock the door. If this is the case, replace them with new ones and see if that fixes your problem.

What to do if your car alarm keeps going off when you lock the car?

If you find that your car alarm keeps going off when you lock the car, it could be the result of a few different factors. Make sure that the battery is fully charged. If it isn’t, your car’s systems won’t be able to communicate with each other properly, which means they may not be communicating with each other at all.

Next, check your fuses. Fuses are what protect your car’s electrical system from overload or damage by absorbing excess voltage and keeping it from damaging any other part of your car’s electrical system. If one of them has blown out, you’ll need to replace it before you can use any functions that use electricity—like your lights!

Check for loose connections. A loose connection in your wiring can cause power surges which can blow out fuses or fry other parts of your car’s electrical system. If a wire isn’t connected properly somewhere in your car’s wiring system, this could also cause issues with how well things communicate with each other across those wires.


There are a few things that can cause your lights to not flash when you lock your car. The first thing is the door switch, which is located in the door itself. If this switch isn’t working correctly, it could prevent your lights from flashing. The second thing could be the wiring in your vehicle. If the wires aren’t connected correctly or if they’re damaged, it will prevent the lights from flashing.
