Key Fob Got Wet And Alarm Keeps Going off

Last Updated on February 3, 2023 by Ryan

If your key fob gets wet, the alarm may go off. To fix this, dry the key fob with a towel and remove the batteries. Let the key fob air dry for 24 hours before reinserting the batteries.

If the alarm still goes off, contact your dealership or car manufacturer.

If you have a key fob that gets wet, it’s important to dry it off as soon as possible. Otherwise, the alarm might keep going off. Here are some tips for drying out your key fob:

1. Remove the batteries from the key fob. This will help prevent any further damage to the electronics. 2. Use a hairdryer on the low setting to slowly and evenly dry out the key fob.

Don’t hold it too close, or you could melt the plastic casing. 3. If possible, open up the key fob and remove any electronic components. Lay them out on a towel or other absorbent surface to dry completely.

4. Once everything is dry, reassemble the key fob and reinstall the batteries. Hopefully, it will now work properly!

What Happens If You Get Your Key Fob Wet?

If you get your key fob wet, there are a few things that could happen. The first is that the key fob could stop working entirely. This is because water can damage the circuitry inside the key fob.

If this happens, you will need to replace the key fob. Another possibility is that the key fob could become intermittent in its functionality. This means that it may work sometimes, but not others.

This is also due to water damage and will require a replacement key fob eventually. Finally, if you only get your key fob wet and do not drop it or otherwise damage it, then it should continue to work as normal once it dries out completely. However, if water does enter the casing of the key fob, then it is possible for corrosion to occur which can lead to malfunctions down the road.

How Long Does It Take for a Key Fob to Dry Out?

A key fob is a small, handheld device that typically uses radio frequency identification (RFID) to work. Many newer cars come with key fobs that allow the driver to remotely unlock and lock the doors, as well as start the car’s ignition without having to physically insert a key. If you’ve ever accidentally dropped your key fob in a puddle or left it out in the rain, you may be wondering how long it will take for it to dry out and start working again.

The answer depends on a few factors, such as how wet the key fob got, what type of materials it’s made of, and how quickly you can get it to dry out. If your key fob only got slightly wet from being caught in a light rain shower, for example, it likely won’t take long for it to dry out on its own. However, if it was submerged in water for an extended period of time or if it’s made of absorbent materials like leather, then drying it out completely may take longer.

To speed up the drying process, you can try using a hairdryer set on low heat or placing the key fob in a sunny spot. You’ll also want to make sure that all of the Key Fob’s compartments are open so that air can circulate inside and help dry things out faster. Once your key fob is dried out, be sure to check that all of its functions are working properly before using it again.

Why Does My Key Fob Alarm Keep Going Off?

If you’ve ever wondered why your key fob alarm keeps going off, you’re not alone. There are a few different reasons why this might happen, and we’re here to help you troubleshoot the issue. One reason why your key fob alarm might keep going off is because the battery is low.

When the battery starts to die, it can cause all sorts of electronics problems, including making your alarm go off randomly. If this is the case, simply replacing the battery should fix the problem. Another possibility is that something is interfering with the signal from your key fob to your car’s alarm system.

This could be anything from another electronic device like a garage door opener to something as simple as a metal object in your pocket or purse. If you think this might be the issue, try moving any potential interference away from your key fob and see if that stops the false alarms. Finally, it’s possible that there’s an issue with your car’s alarm system itself.

How Do I Stop My Car Alarm from Going off With Key Fob?

If your car alarm goes off when you use your key fob, it may be because the fob is not properly synced with the car. To fix this, you will need to resync the key fob with the car. Here’s how:

1. Sit in the driver’s seat and close all doors. 2. Insert the key into the ignition and turn it to the “On” position (do not start the engine). 3. Press and hold down the panic button on your key fob for at least three seconds.

After a few seconds, you should hear a chirping sound coming from your dash or center console area. This means that your alarm is resetting itself and is ready to be re-synced with your key fob. If you do not hear this chirping sound, try step four again.

Accidentally Washed Key Fob

If you have accidentally washed your key fob, there is no need to worry. There are a few steps you can take in order to fix the issue. First, remove the battery from the key fob.

Next, use a can of compressed air to blow any water out of the key fob. Once you have done this, allow the key fob to dry for 24 hours. Finally, reinsert the battery and test the key fob to see if it is working properly.

Key Fob Got Wet And Won’T Work

If your key fob has gotten wet and won’t work, there are a few things you can do to try and fix it. First, if the key fob is still wet, try wiping it off with a dry cloth. If that doesn’t work, remove the battery from the key fob and let it dry out for a few hours (or overnight).

Once the key fob is dry, reinsert the battery and see if it works. If not, there are a few other things you can try. One thing you can try is holding down the unlock button on your key fob while inserting the key into the ignition.

This will sometimes bypass any issues with the key fob itself and allow you to start your car. Another thing you can do is use an existing spare key (if you have one) to start your car. Once your car is started, you can then use your regular key fob to lock/unlock your doors and activate/deactivate your alarm system.

If neither of those solutions work, then unfortunately you may need to get a new key fob from your dealership or auto locksmith.

Wet Key Fob

If your key fob gets wet, there are a few things you can do to try and salvage it. First, remove the battery and let the key fob dry out completely. If possible, put it in a sunny spot or use a hair dryer on low heat to speed up the drying process.

Once it’s dry, reinsert the battery and see if it still works. If not, you may need to replace the key fob entirely. In the meantime, while your key fob is drying out, you can use your car’s emergency key.

Most cars come with a physical key that can be used to unlock the doors in case of an emergency. The location of this key varies by car make and model, so consult your owner’s manual for more information.


If your key fob gets wet, it’s important to dry it off as soon as possible. Otherwise, the alarm might keep going off.
