buy a new one from where you bought it from
before you spend too much money..check the solder and.try this.
On the inside of the keyless remotes, there are rubber buttons, those rubbers buttons are brushed with metal of some sort so that it reacts with the motherboard, when the remotes get older this metal wears off...so try this, it worked for me...
I superglued foil paper to the back of the button (the parts that touches the motherboard when pressed) and replaced the batteries... it worked like a charm, I used an awl and a hammer to make perfectly round piece of foil and just glued it onto the back of the button... i'd try this first before spending any real money
You do not have to reset the keyless remote after battery replacement.
No.
Replaced the battery in the remote.
Dead battery. Broken solder joints. Limited to NO contact with remote buttons to circuit board.
Open the keyless remote and you will see the battery take it out and replace it with the same size.
Hold the lock and unlock buttons simultaneously for 7 to 10 seconds. The locking mechanism on your car should activate and your remote should be synchronized. Just did this on my 2003 Tahoe. You definitely do have to resynchronize our keyless entry remote after changing the battery. The car manual clearly states that you need to (although it doesn't say how).
DID YOU TRY CHANGING OUT THE BATTERIES ON THE REMOTE??
Cut open the remote with xacto knife , unsolder and replace the battery.
Your keyless remote might not work for your 2002 Chevy Tahoe because the battery in the remote is dead. You can replace this battery by prying the remote cover off of the back of the remote or by removing the screws holding the cover closed.
Most keyless remotes just snap together. Look closely for a small notch in the seam of the remote. A regular watch style battery is inside.
The battery in the keyless remote of a 1999 Mercedes E320 is changed by prying off the back cover and lifting the battery out. The battery will typically last 2 years or more under normal use.
replaced battery and now remote doesnt work . how do you reprogram remote
