When it comes to car keys, particularly the electronic ones like transponder keys or smart keys, we often assume that they are designed to withstand various conditions. However, contrary to popular belief, car keys are not waterproof. Dropping a key fob into water can have severe consequences, such as damaging the circuit board, leading to malfunctions or even complete failure. Immediate action is crucial in order to prevent further damage when a key fob gets wet. In this article, we will explore the options for dealing with a wet key fob and provide helpful tips to fix water-damaged keys. Additionally, we will highlight the importance of preventing key fobs from getting wet in the first place. So if you’ve ever wondered about the waterproof capabilities of your car keys, keep reading for valuable insights on this subject.
Are Car Keys Waterproof?
Car keys have come a long way since the traditional mechanical keys that were used to simply unlock and start vehicles. With the advancement of technology, electronic car keys have become the norm, offering convenience and added security. However, one question that often arises is whether car keys, especially electronic ones, are waterproof. In this article, we will explore the vulnerability of electronic car keys to water damage, the potential damage caused by water, immediate actions to take when a key fob gets wet, repairing a wet key fob, and finally, how to prevent water damage to key fobs.
The Vulnerability of Electronic Car Keys
Car keys, especially electronic ones like transponder keys or smart keys, are not waterproof. Unlike traditional mechanical keys that can withstand exposure to water to some extent, electronic car keys contain sensitive components such as a circuit board that can easily be damaged when exposed to water. This vulnerability makes them more susceptible to malfunction or complete failure if they come into contact with water.
Potential Damage Caused by Water
Dropping a key fob into water or exposing it to moisture can have detrimental effects on its functionality. When water infiltrates the circuit board of a key fob, it can cause the electrical components to short circuit or corrode. This can result in a range of issues, including an inability to unlock or start the vehicle, unresponsive buttons, or intermittent functionality. In severe cases, the key fob may become completely inoperable, requiring a replacement.
Immediate Actions to Take
When a key fob gets wet, immediate action is necessary to prevent further damage. The first and most crucial step is to remove the key fob from the water source as quickly as possible. Leaving it submerged can prolong exposure to water and exacerbate the damage. Once removed, it is important to dry the key fob thoroughly to minimize the risk of corrosion. Simply wiping it with a towel may not be enough, as water can seep into crevices and hidden areas.
Repairing a Wet Key Fob
If your key fob has gotten wet, there are a few steps you can take to try and repair it before seeking a replacement. The first step is to gently shake out any excess water. Be careful not to shake it too vigorously, as this may cause further damage. Next, use a dry towel to absorb any remaining moisture on the surface of the key fob. It is important to avoid using heat sources such as hair dryers, as excessive heat can damage the internal components.
To further minimize the risk of damage, opening the key fob and removing the battery can be helpful. This will allow air to circulate and aid in the drying process. However, it is crucial to handle the circuit board with care to avoid causing additional damage. After removing the battery, clean the key fob and circuit board with isopropyl alcohol. This can help remove any residual moisture and prevent corrosion. Once cleaned, allow the key fob to air dry completely before reassembling it and attempting to use it again.
Preventing Water Damage to Key Fobs
While knowing how to repair a wet key fob is useful, it is best to prevent key fobs from getting wet in the first place. Here are some practical tips to help prevent water damage to your key fob:
-
Keep it dry: Avoid exposing your key fob to water whenever possible. This includes avoiding activities such as swimming, boating, or even doing dishes while carrying your key fob.
-
Invest in a waterproof cover: Consider purchasing a waterproof cover or case specifically designed for your key fob. These covers provide an additional layer of protection and can help prevent water from seeping into the key fob.
-
Store it properly: When not in use, store your key fob in a dry and secure location. This will help reduce the chances of accidental exposure to water.
-
Check for hidden mechanical keys: Some key fobs may have a hidden traditional mechanical key that can be used as a backup in case the electronic components fail due to water damage. Familiarize yourself with your key fob and locate this backup key if it is available.
In conclusion, car keys, especially electronic ones, are not waterproof. Dropping a key fob into water or exposing it to moisture can cause damage to the circuit board, leading to malfunction or complete failure. When a key fob gets wet, it is crucial to take immediate action to prevent further damage. Repairing a wet key fob can be done by shaking out excess water, drying with a towel, opening the fob to remove the battery, and cleaning with isopropyl alcohol. However, it is best to prevent key fobs from getting wet in the first place by keeping them dry, investing in a waterproof cover, storing them properly, and checking for hidden mechanical keys. By following these precautions, you can ensure the longevity and functionality of your electronic car keys.
