What type of battery for suzuki swift keyless remote?

SOURCE: How do I program my new Suzuki keyless entry remote to work with our new SUV?

I bought a remote the other day and got these instructions with it. They worked!

1. Make sure vehicle is in Park
2. Press Vehicle Information button (has the icon of a car and an 'i')until 'PRESS *check mark* TO RELEARN REMOTE KEY' displays.
3. Press set/reset button. The message 'REMOTE KEY LEARNING ACTIVE' will display.
4. Press and hold the lock and unlock buttons on the transmitter at the same time for about 15 seconds. A beep will sound indicating that the transmitter is matched.
5. To match additional transmitters at this time, repeat Step 3. Each vehicle can have a maximum of four transmitters matched to it.
6. To exit the program mode, you must cycle the key to LOCK.

Unfortunately, the keyless entry remotes and OE systems usually require a dealership to service them. Sounds to me like they need to re-set the alarm

They need to be reprogrammed. You can take the car and the remotes with you to a dealership and have them reprogrammed. Make sure to take both remotes with you.

If you go to a place that sells all kinds of battery they will usually change it for you. But a smaal flat head screw driver also works
