Changing your remote control battery
Each remote control contains a single long-life lithium
battery (CR1616). This battery will normally last at
least 12 months. Normal range for the remote control
is around 10 metres. As the battery within the remote
control comes to the end of its life, you will notice
a reduction in its range and the battery should be
replaced.
1. To replace the battery remove the small screw
from the 'key end' of the remote and split the two
halves of the case.
NOTE: Take care not to lose the screw and ignition key
blade/transponder if the key conversion has already
been carried out.
2. Lift the printed circuit board from the remote.
3. Slide out the circular CR1616 battery from its
holder noting the polarity.
4. Maintaining the polarity of the battery, slide the new
battery into the battery holder.
5. Fit the PCB into the rubberised holder and check
the OE transponder chip is still located within the
to half of the casing, if fitted.
6. Fit the assembly into the top casing so the GREY
and BLACK buttons drop into their respective holes.
At this stage it is a good idea to press the remote
control buttons to check they are operating correctly,
this will be shown by the LED on the remote control
illuminating
7. Refit the ignition key blade into its holder, if required.
8. Clip the bottom half of the casing to the top half,
replace and tighten the screw holding the two halves
securely.
