Test the Functions
Now, test your key fob. Stand close to your car and try the lock, unlock, and ignition functions. If it works, congratulations! You saved your key fob from water damage.
Signs of Permanent Damage
Unfortunately, sometimes water damage can be irreversible. Here are some signs that your key fob might not be salvageable:
Non-responsive Buttons
If the buttons do not respond or require a lot of pressure to function, it could indicate that moisture has corroded the connections.
Physical Corrosion or Damage
If you see signs of corrosion on the circuit board, it’s a sure sign your fob has sustained permanent damage.
Battery Issues
If your key fob only works intermittently after drying, the battery itself may have taken a hit, leading to decreased performance.
Preventive Measures for the Future
To avoid the hassle of dealing with a wet key fob again, it’s helpful to implement some preventive measures:
1. Invest in a Key Fob Holder
Using a durable, water-resistant key fob holder can help shield your device from accidental water exposure.
2. Be Mindful of Surroundings
Always be aware of where you’re setting your key fob down. Puddles, sinks, and countertops with drinks can be traps for carelessly placed fobs.

What should I do immediately after my key fob gets wet?
If your key fob gets wet, the first step is to remove it from any moisture immediately. If it was submerged, take it out of the water and shake off any excess liquid. Open the key fob, if possible, to access the internal components. If your fob has a removable battery, take it out to prevent any short circuiting.
Once you’ve got the fob opened up, use a lint-free cloth or towel to gently dab away any visible moisture. It’s crucial not to rub too hard as that might push water further inside the device. After drying the outer surfaces, consider placing the key fob in a bowl of uncooked rice or silica gel. These materials can help absorb any lingering moisture.
Can I use a hairdryer to dry my key fob?
Using a hairdryer to dry your key fob is not recommended. The heat generated by hairdryers can damage the delicate electronic components inside the fob. Additionally, too much heat can warp the plastic casing or degrade the adhesive that holds the fob together.
Instead, the best methods for drying involve air-drying and using desiccants like rice or silica gel packets. If you need to speed up the drying process, place your key fob in a warm, dry location where it can naturally dry out without exposing it to direct heat.
How long should I wait before testing my key fob after it got wet?
After your key fob has been exposed to moisture, it’s advisable to wait at least 24 to 48 hours before attempting to use it again. This waiting period allows ample time for moisture trapped inside the fob to evaporate completely, reducing the risk of electrical shorting.
While waiting, ensure that your key fob is in a safe and dry place. Avoid turning it on during this time as doing so may cause permanent damage if there is still moisture inside. Humidity levels can affect drying time, so if you’re in a humid environment, you may want to extend the waiting period.
What signs indicate that my key fob is damaged?
You might notice several signs indicating that your key fob is damaged after exposure to water. One of the most common signs is if the fob fails to respond when you press buttons, showing that the internal circuit board may have shorted out. Additionally, look for corrosion on the battery or connectors, which can indicate internal damage.
Another sign of damage can be erratic behavior of the fob, such as buttons working intermittently or additional functionalities failing. If the fob has physical damage, such as cracks or signs of water inside the casing, this is also a clear indication that it may not function properly again.
Can I fix my wet key fob myself?
Yes, you can attempt to fix a wet key fob yourself, but success may depend on the extent of the damage. Start by disassembling the key fob carefully and removing the battery. Use a lint-free cloth to blot away as much moisture as possible. If you have electronic cleaner spray, you can use that to clean any corrosion found on the circuit board.
