The reasons of your car key button is not working
Cars are one of the most important assets people own. If you care for your car well, it should start reliably in all weather and after many trips. Sometimes, your car key button may not work right. Learn about the 4 reasons of your car key button is not working.
However, there are times when your vehicle’s technology and equipment fail for reasons beyond your control, like your car key button not working. Experiencing an extremely frustrating scenario, when walking out to your car in the morning and suddenly realizing the car key button is not working, prompts the question: What causes this inconvenience? Moreover, is there a quick fix? These could be some of the 4 reasons why your car key button is not working.
We have summarized the four most likely reasons why your car key button is not working:
- Dead batteries
- Defective key fob
- Broken car door lock
- Other electrical issues
1. Dead Batteries
With a car key button not working, the easiest and cheapest solution is to change the batteries. This may not solve the issue, but it is worth trying as a troubleshooting measure to figure out what the actual problem is. Quite often, dead batteries are the reason for a car key button not working.
Changing the batteries in your key fob is simple. All you need to do is take the shell apart, look at the battery and find the part number. Take a picture or write that number down and go to an auto parts store for a replacement. Major auto parts retailers should have a matching battery in their inventory, as will most auto locksmiths.
2. Damaged Key Fob
The dead batteries inside the key fob are only part of what could be the cause of a car key button not working. Gradual wear and tear from continual usage of the key fob itself may be the real issue. Worn buttons are a common sign of overuse. After a certain amount of years, a car key button not working is normal, which could be one of the 4 reasons of your car key button is not working.
The key fob may not work after a battery change due to deteriorating buttons on the remote. This is because the buttons on the key fob use contacts that send signals to a circuit board when pressed. Consequently, the contacts can wear down or the buttons can deteriorate, preventing the contacts from making proper contact.
The most obvious sign of a worn button is when the plastic has fallen apart and the contact is exposed. Consequently, in some instances, not all of the car key buttons are working. Perhaps the key fob will not unlock doors; however, the lock button still works. Therefore, you might have a worn unlock button causing the problem.
There is also the possibility the car key buttons not working is a result of how you are pressing the buttons. Damaged buttons can get finicky and may only work properly if you push them a certain way. To visualize this, think of the buttons on the remote to your TV. The most used buttons can sometimes get stuck, or you have to push them with more force than the others.
One useful method to identify the issue with your car key button not working is to test a spare remote. This can help determine if the problem lies elsewhere, as testing two key fobs for the same issue may indicate that it is not due to a worn button or contact problem.
Modern cars have advanced technologically. Keyless ignition fobs in these cars need complex solutions to fix issues. If a modern car key button doesn’t work, reprogramming the fob can be difficult due to enhanced security measures.
Key fobs for newer vehicles use various signal encryption methods to keep criminals from capturing the car key signals and making unauthorized fobs. This requires the use of proprietary equipment restricted to locksmiths and dealerships exclusively
