Replace the battery in the same direction as the old one (the positive side facing upwards towards the buttons). After reassembling the fob, test its start, lock and unlock functions to ensure that the new battery was placed correctly.

Fob Is Not Programming
Car key fobs are a convenient option that lets you unlock your car doors and then start the engine. They can also be a source of frustration when they stop working or seem to function intermittently. In some instances the issue may be as simple as replacing the battery however, in other instances it may require a more complicated repair. The first step is to determine the reason why the fob isn't working correctly.

Other issues could arise when the key fob isn't able to sends a clear signal. This could be the result of a key is damaged or the battery is dead. In any case, attempt to reconnect the key with your vehicle. This can be accomplished by following the directions provided on the key fob. It is also recommended to carry a spare car key in case the primary key is lost.
The fob may not be receiving a strong signal from the vehicle. This can be due to an insufficient battery in the car or interference from wireless devices, or an antenna issue. By using a remote tester you can test the fob and check if it's the cause of the issue. If the tester doesn't light up when one of the buttons is pressing, the battery may need to be replaced or the fob may be damaged.
Another possible reason for a fob not sending the right signal is that the immobilizer system in your car is blocking it from doing so. This could happen if the fob's programming isn't correct to your vehicle, or it's an issue with the software.
If you're not able to troubleshoot the problem or it's not worth the effort of trying to repair the fob, you should look into buying a replacement. Many online retailers offer affordable options and some are delivered right to your home.
