Thread: 2008 puma 110 engine immobiliser

Just checking perceptions... When you changed the fob battery did you follow the process in the user manual?

(There is this whole convoluted process that doesn't quite require a blood sacrifice, but does involves being in the car near the ignition switch when you actually change the battery else risk of losing synchronization with the ECU. And a bunch of steps to follow to resync if you did follow the process and change the battery inside the vehicle)

Just asking to establish some common ground here - if you just took the fob to the local hardware or Mr Minute and changed battery you might have caused yourself some added grief.

I changed them in the back of the car. But I am now thinking that may be to far away from ignition.
Was not aware that changing the battery had a set procedure.
How do I connect them to the ECU again.

This is from owners manual for a MY2013 - yours may be different. Step 7 below re syncs fob if all else ok

REMOTE KEY FOB BATTERY REPLACEMENT
When the battery is due for replacement the following symptoms will be apparent:
•The remote control will work only with a second press of the unlock button.
•The indicators will not flash when the alarm is disarmed.
•Alarm indicator in instrument pack continues to flash rapidly after initial ten second period of rapid flashing.

The remote control battery must be changed while inside the vehicle.

DO NOT remove the battery until you are ready to install the replacement. Battery replacement must be completed within five minutes otherwise the EKA code will have to be entered before the remote control can be synchronised to the vehicle.

Fit a new Land Rover STC4080 or a Panasonic CR2032 battery.While sitting in the driver’s seat, follow the process to replace the battery:
1.Insert the key into the starter switch and turn to position II. Return it to position 0and remove the key.
2.Starting at the key ring end and using a small coin or screwdriver, carefully prise apart the remote control.
3.Slide the battery out of its retaining clip. DO NOT touch the internal parts
4.Press and hold one of the remote control buttons for at least five seconds to drain off any residual power.
5.Fit the new battery ensuring that the + symbol is facing up. Finger marks on the battery flat surfaces may adversely affect its performance. Ensure that the battery is clean.
6.Press the two parts of the remote control casing together, ensuring that they are fully joined. Moisture and dirt must not be allowed to enter.
7.From outside the vehicle, operate the lock button at least four times. This will synchronise the remote control with the vehicle.
8.Press the unlock button once to unlock.The remote control is now ready for use.Note: Used batteries must be disposed of correctly as they contain a number of harmful substances. Seek advise on disposal from your local authority.

I had the battery die in a fob last week and followed the above to replace batteries in both my fobs

I was wondering why my blinkers stopped flashing when unlocking !
Cheers

I tried pressing the lock button lots of times but still no luck. I did not replace with suggested make of batteries so will buy Panasonic ones today. See if that makes a difference.
My battery in the car went flat last week could a low battery cause this problem.

I couldn't find Panasonics so I used Eveready CR2032. Working fine.

Is there any way of disconnecting or switching off the immobiliser
