HELP. 2013 Defender 2.2 puma immobiliser fault

Hi all my 2013 2.2 puma is playing up, it cranks for a second then non start immobiliser red light stays on solid, here’s what I have tried
1. Changed fob battery and checked fob is transmitting a signal
2. Plugged in diagnostics and no communication with immobiliser module (every thing else talks ok no fault code in engine ecu)
3. Checked every fuse and relays all good and dry
4. Checked 10as box connectors all good and box is dry and lives and earths all seem present at 10as
5. Can get it to start by flasher battery terminals but back to fault once switched of again
6. Don’t have EKA and can’t reade out the ecu due to non communication with 10as

I’m thinking 10as box fault So I guess my question is there a bypass for the immobiliser side

Thanks in advance Paul

Hi
short answer is no

I had a similar problem with my MY13 110. 2.2 the 10as in my car is the early puma BLACK 10as.

in the end, I have to replace the 10as and upgrade the entire system, inlcuding key fob...and now I have a shiny one like the evoque keyfob (or late puma key fob

Honestly, man, even if there was a way to deactivate immobilizer & alarm (and take that car right away

), how could you want us to tell it to anyone on the internet ? Don't you want your Land Rover to be safe ?

Just go to your JLR reseller, prove your ownership + identity and get your EKA code.

P.S. there you're asking very difficult questions while having just 8 posts ...

Thanks for all the replies, in my case the 10as was just programmed out for £60 and problem solved for ever then I added a insurance approved cat 1 aftermarket alarm which is a must and off course the factory key chip side stays active. Thanks again

Just to add, in our case the fault with my car would not let you communicate diagnostically with the immobiliser or enter the EKA code and after watching the guy reprogram my car in 15 minutes I would not rely on the factory system to protect any Defender

I've got this fault now (and mines a 2015 with the later type ECU). Its currently stuck on the ramp in a local independent specialists. Before I spend £800 on new ECUs and keys, I'm interested to hear more about the coding guy who worked around it. Who was it?

Just a thought - but you dont have both key fobs in the cab at the same time - this will stop the engine starting if they are to close together.

Just a thought and shared experience ..

I've only got one coded key. I bought a spare but they were unable to code it.
It seems as if the ALM has corrupted its software, probably due to car battery going flat. Its now locked down and diagnostics can't see it.

it looks like the only options are a new system from LR at about £800. or a bypass which deletes the immobiliser/alarm/central locking but reliably starts the vehicle for a lot less. I'm now wondering if fitting an aftermarket alarm alongside the bypass would be a preferable way of solving the obvious weak point. Glad I'm not halfway across the Kalahari Desert hey
