Push the tip of a flathead screwdriver or coin into the slot, and then move it around the edges. Then, you can insert the new battery and then snap the two halves of the fob shut. After you've completed the process recycling the old battery at a nearby collection site.
If the new battery does not solve the issue, it may be a problem with the RFID system on the key fob itself. Most vehicles that have an ignition system that uses a push button require the fob to be positioned close to the barrel of ignition to verify its presence and send the proper signal for the vehicle to start.

Faulty Transponder Key
A transponder key that is faulty could have severe consequences. Transponder keys are different from traditional metal keys that engage the ignition mechanically. They are equipped with an electronic microchip that transmits an individual number to the immobilizer system of the car to verify its identity. This adds an extra layer of security, which reduces the risk of thefts and other vehicular crimes. Transponder keys, as with any electronic device, are susceptible to various problems related to the function of the chip.
Transponder chips are delicate and even a small physical damage will affect their capacity to function. It is essential to check your transponder keys to see if there are signs of wear, since these could be the reason for a malfunctioning immobiliser.
In addition the internal microchip inside the transponder key is sensitive to water and other environmental conditions, which could affect its ability to communicate correctly with the immobilizer system of a vehicle. It's therefore important to keep the key fob and the keychain as far from water as possible.
It is important to keep in mind that the transponder car key is programmed specifically for a specific vehicle. Changing any sensitive parts could lead to compatibility problems that could compromise its function. Therefore, it's best to avoid any kind of modification to a vehicle key in the absence of the appropriate knowledge and tools to do it safely and effectively.

Antenna or Receiver is damaged.
The transponder chip inside your car key transmits an electronic signal that is interpreted by the ECU to confirm that it's the right key to start the car. The immobiliser stops the engine from starting if it's not the correct key. This is to prevent thieves from gaining access to your car's engine using stolen or cloned keys.

Radio frequency interference (RFI) can be caused by communications equipment and transmitters such as computer systems, cable television systems and digital devices, large electrical equipment or lighting systems. It's also possible that the coaxial antenna cable is damaged or disconnected. This can occur when pets wander around the house, or if the cable is twisted or damaged during installation.
Another reason that the antenna might not be working is that the receiver might be too far from the antenna. You can test this by connecting the receiver to a different antenna. If the error message remains, you might require a new antenna or reroute the coaxial cable.
Antennas aren't good, but they could be twisted, pinched, or come loose from their connectors, causing the RF quality of the signal to decrease. Make sure there's nothing between the receiver and antenna, like a surge protector, splitter, or splitter that could impact the signal strength.
If you use the EEPROM method to program the car key, you will require the removal of specific modules (security components) from your vehicle and then read the "password" from them. This requires expertise as the information could be corrupted. A professional auto locksmith has a thorough understanding of the circuit board and can minimise this risk by reading the data directly from the module using a specific tool.
Faulty Electronics
Many modern cars have security systems that stop them from starting the engine in the event that they don't have a car key or remote. These systems use RFID (Radio Frequency Identification) or immobiliser controls to authenticate a fob or key that is placed into the ignition.

If the codes match the engine will begin and the immobiliser will shut off. If the immobiliser is unable to detect the signal that it is looking for, the engine will not start and you could be left stranded.
