Key fobs are quintessential to the modern driving experience, and for good reason. They allow you to lock and unlock your car doors, start the engine, and open the trunk remotely. With the convenience they offer, it’s no surprise how integral these devices have become to the automotive world. Virtually every automaker offers them now as a standard accessory for their vehicles. But even key fobs of the most luxurious brands can stop working sometimes, which can prove extremely frustrating. Let’s look at the reasons key fobs break down and how you can fix them.
Common Causes for a Cadillac Key Fob To Stop Working
There are several reasons why a Cadillac key fob might stop working. Let’s examine some of the most common causes.
Battery Issues
The most common reason Cadillac key fobs stop working is battery depletion. While key fob batteries are designed to last for long periods, they do run out of power and will need to be replaced eventually. So, if your Cadillac’s key fob suddenly stops working, there’s a good chance its due to a depleted battery.
Dirt and Debris
Accumulated dirt and debris in the crevices of your Cadillac’s key fob can cause signal interference, resulting in unresponsive buttons. This is why it’s important to clean your key fob often and store it in a protective case when not in use.
Mechanical Issues
While luxury key fobs are built to withstand physical impact from drops, they are by no means indestructible. When dropped too often, even the most robust key fobs can sustain damage to their internal components.
Interference or Signal Issues
It’s not uncommon for a key fob to stop working due to signal interference. If your key fob functions fine when in close proximity to your Cadillac but stops working when you move further away, you’re more than likely dealing with a signal issue. You can confirm whether this is the case by testing it in an area without tall buildings and other vehicles.
How To Fix a Key Fob That’s Not Working: A Step-by-Step Guide
A key fob that stops working can leave you stressed and worried. The good news is, there are several things you can do to diagnose the problem and try to fix it.
Step 1: Check and Replace the Battery
The first thing to do when attempting to troubleshoot a key fob is to perform a battery check. To do so, you’ll need to open the key fob to access the battery compartment.
Start by locating the tiny release button on the side of your Cadillac’s key fob case. Pressing this button will pop open the case to reveal the metal key. Take out the key to reveal a small opening, then use a flathead screwdriver to pry open the key fob case. Inside, you should see the circuit board on one side and the battery on the other. Inspect the battery for signs of damage or corrosion. You can also test the battery using a multimeter to see the voltage reading. If the battery is damaged or the voltage reading is too low (below 3 volts), you need to replace it. Most Cadillac models use a CR2032 battery, which you can purchase at your local hardware store.
Once you have the new battery, simply insert it into the battery compartment with the positive side facing down. When the battery is in place, pop the case back on and test the fob. If the battery was the issue, it should work perfectly.
Step 2: Clean the Key Fob
Cleaning your Cadillac’s key fob is a simple and low-cost way to ensure it continues to function optimally. To do so, you’ll need a microfiber cloth and isopropyl alcohol. Start by opening the case using the method outlined in the previous section and removing the battery. Doing it this way is essential to avoid damaging the battery.
After removing the battery, dampen the microfiber cloth with alcohol and gently wipe every part of the key fob. You can also use a cotton swab dipped in alcohol to wipe difficult-to-reach areas. Remember not to use too much alcohol, as doing so can damage your key fob’s buttons.
Next, wipe the key fob with a dry microfiber cloth to remove any excess moisture. When you’re done, reinsert the battery and pop back the case before testing to ensure it’s working correctly.
Step 3: Test the Button
Testing whether your key fob button is working is straightforward. Simply hold the key fob against your Cadillac’s push-button start or steering column and press the button on the fob. If your car responds by locking or unlocking the doors or starting, it means your key fob button is not the problem.
Step 4: Reprogramming the Key Fob (Optional)
If your key fob still isn’t working after you’ve checked, replaced, or cleaned the battery, there’s a possibility it has lost its connection to your vehicle. In this case, you’ll need to reprogram it to get it functioning again. Check your owner’s manual for specific steps to reprogram your Cadillac’s keyless entry system.
