Car Key Repair - How to Fix a Dead Remote
Car remotes offer excellent convenience for drivers. They allow you to unlock doors, gain access to trunks, and even start the engine. But, these remotes sometimes stop working at odd times.
If you notice that your key fob not working, you can try a few quick fixes before going to the dealership. These suggestions could save you money.
Keyless Entry System
You don't have to look for keys in your pockets or purse. Just walk to your car, push the button on the keyfob, and the doors will unlock and the engine will get started. It's an easy feature that makes driving a car more comfortable and secure. But just like any device that has a keyless entry system, the keyless entry system may fail due to frequent use or due to other reasons. If you're having problems with your system, you can either go to the dealer or contact an locksmith.
The way a keyless entry system functions is by releasing radio signals and then searching for a response signal from the key fob. If the system recognizes the signal, it's triggered to unlock the vehicle doors and activate the computer onboard. Some systems include a second receiver on the car's trunk that will open automatically when you waggle your foot on it.
Each key fob is given a unique digital identification code by the manufacturer. The fob is programmed with a unique process called "programming". This involves turning on the ignition of the car repeatedly in a certain sequence, and could require pushing or pulling buttons or levers, or removing the fuse.
When a key fob is programmed to your car's keyless entry system it transmits the digital identity code, along with a function code that tells the car what to do (lock or unlock the trunk, or open the trunk). The car's receiver confirms the identity of the transmitter through an authentication and encryption process. The computer on board will allow the vehicle to be opened and start the engine if it is authenticated.
A clever criminal could intercept and use the code transmitted between the keyfob and the vehicle. This will require an instrument that records the transmission, and then retransmits it when the system doesn't anticipate it. The majority of keyless entry systems employ the rolling code method to combat this. This ensures that each new signal from a transmitter received by a car has a counter that is different from the previous one.
Batteries
A dead battery is the main reason for a car remote to not work. It's an easy and cheap fix in the event that you have a spare key fob on hand to replace the old one with. Most fobs are powered by watches-style batteries, which can be bought at big-box stores or hardware stores for less than $10. A quick search of the internet or your car's owner manual should provide instructions on how you can disassemble the fob that you have been using and replace the battery.
Once you've removed the battery, make sure not to damage any of the circuits or antennas in the case. They are likely holding the key fob's program to your car's specific model, and messing with them will render it unprogrammable (and likely to fail). If you must move the key fobs, take care. Certain key fobs could have fasteners which can easily open and scatter key fob pieces across your living space.
Most key fobs have one hole that allows the screwdriver or another pry tool to open the case, but it's a good idea wedge your pry tool around the outside of the case first, like you would peeling an orange or apple. Don't apply too much pressure, as the case of the fob is usually constructed of plastic and could crack or break if you apply too much pressure to it.
If you're ready to replace the battery, make sure to match the size and type to your key fob. Certain fobs require two batteries, while others have just one. Using Read Even more can quickly render your remote key fob ineffective.
If the issue persists, you can try again using your fob's key after installing the new battery. If it doesn't work then you'll be required to determine if your fob is suffering from an issue that is more complicated and requires professional diagnosis. If this is the case, you might need to have it reset by a dealer or purchase a new key fob completely.
Buttons
The buttons on your key fob could be tiny but they're loaded with electronics. Therefore, it's not surprising that they're destined to fail from time to time. If the car key button suddenly stops working, you can usually fix it yourself.
One of the most common reasons that a car key remote fails to function is due to dirt or dust that has become lodged between the buttons. To clear this up remove the batteries and scrub each button by using a cotton swab, coated with rubbing alcohol. Make sure to dry them completely before reinstalling batteries.
It's possible that the key fob was harmed by accident, such as being dropped on concrete or unintentionally scratched by something sharp. If this is the case using a different key fob to test its functionality could reveal that the one you have been damaged and requires to be replaced.
The door lock sensor could have stopped working in your vehicle. This sensor is a small metal part that is attached to the key fob's door lock button. It's not uncommon for it to break due to weather conditions or long usage. To reactivate the sensor simply press your key button several times without locking or unlocking your doors to reset it.
If all other options fail, you can always test the operation of an extra key by trying to lock and unlock your doors using it. If the spare key does not work, you may need to call a locksmith 24 hours a day who offers automobile key repair to make your remote work again.
If your car's key fob is working, but it's still not locking or unlocking the vehicle, you may try to reprogram your computer system. If you've had the same key fob for a time, it may need to be reset every few months to continue working with your vehicle. It's not the most ideal solution, but it's better than having to purchase an entirely new remote.
