Instructions are in the manual. I changed the batteries in the two fobs I have. Not hard at all.

1. Take the integrated key out of the remote control.
2. Push in the catch with the key.
3. Remove the cover of the battery compartment.
4. Insert a battery of the same type with the positive side facing upwards.
5. Press the cover closed.
