lost keys-only had it a week! now what? bypass immo possible?

**hypobuang** · 1st March 2012, 09:42 PM

Hi guys,
Im up to my neck in it! I need to bypass my immobiliser (or a similar remedy).

last week I bought my first discovery. Its on LPG and a pleasure to drive.
now I've lost the keys and have been quoted $400 from the local LR dealer here in Port Macqyuarie (mid nth coast NSW).

the system had issues to start with. the door locks wouldnt pop all the way up when using the key fob. so you had unlock it with the key. soon as you opened the door the alarm would go off until you put the key in the ignition and turned it around till the dash lit up.

I picked the old girl up cheap. It's got 377 on the clock but the engine runs sweet and the drive train is excellent. tidy interior and has about $500 worth of panel damage.

so what now? I live in the bush so an immobiliser isnt important to me and is more of a hinderance if I have future problems with it. so can it be bypassed? and if so can it be done easily?
I did a search but only came up with some hints on earlier models from overseas, so dont know if the info suits our aussie models. (eg, hotwiring the fuel solenoid and starter, maybe for series1 discos).

the disco is a 2/99 model. I think its a series2. I can post the vin number tomorrow if needed as the books and folder that came with the car is at the locksmiths till the morning. the key is an ordinary old double sided one, not the later looking type).

Im having the barrel repaired as the same locksmith cut me a key today so at least I could lock it. Got the key home and the door lock was so hard to unlock and lock, although the ignition worked ok (just wouldnt start).

I tried the door lock bypass sequence but due to the dud door lock I couldnt get the sequence right. Ill try again tomorrow after I get the lock/key back.

can anyone tell me if I get the bypass sequence right (from on the card I have) and manage to bypass the immo will it be a permanent bypass, or will I have to keep doing the sequence?

sorry for all the questions. I
I've just gone through all these immo problems with a Ducati that I bought damaged from the auctions. I knew I was going to have problems with it, but didnt expect to loose the disco keys so soon!

any help greatly appreciated!

Could be D1 or D2. You haven't said if its petrol or diesel. D1 has 3.9 V8 (says so on top of engine) or 4 cyl diesel. The immobiliser is easy to deal with, it can be bypassed by a simple set of wires. D1's have sideways operating door handles. D2 has 4.0 V8 or TD5 engine, need electronic helping tool to access the ECU. D2 has nice horizontal pull door handles.

sorry,
its a 4litre petrol V8. (no label visible on the engine, but im sure its in the manuals).
so I guess its a D2. and It has the vertical door handles.

I have to pick up some parts for it today from a local discovery guru and hope he has a way to bypass the immo.

If not I guess I'll just have to fork out the 400 to the LR dealer.
just hoped there was an easy solution!

Vertical door handles???

If you use the EKA code, at least you will be able to drive it. See RAVE
Then get a Nanocom and immobilise the immobiliser. I'm fairly sure that can be done.

**hypobuang** · 2nd March 2012, 02:10 PM

oops. horozontal i mean! sorry!
thanks for the pointer on the nanocom. ill chek that out now.
managed to get it started using the EKA code...

deleted my previous comment....

After checking the BBS documentation it is possible to disable the passive immobiliser in the BCU module using the Nanocom.

Passive immobilizer: When enabled with this setting, passive immobilization prevents the vehicle from being started unless a correctly programmed remote transmitter key is used to start the vehicle. This system works whether or not the driver sets the security system into an active state. The BCU immobilizes the engine 5 minutes after the ignition has been switched off, providing the driver�s door is not opened. The BCU will immobilize the engine 30 seconds after it detects the driver's door opening. Immobilization is achieved by the BCU not transmitting the code to the EMS ECU. This code is needed to allow the engine to continue to run after the initial start-up sequence. If the BCU or ECM is replaced, this code will require synchronization with the new unit.

RAVE has this to say about immobiliser function of the TD5 EMS:

Immobilisation system

When the starter switch is turned on, the BCU sends a unique security code to the ECM. The ECM must accept this
code before it will allow the engine to operate. If the ECM receives no security code or the ECM receives the incorrect
security code, then the ECM allows the engine to run for 0.5 seconds only. During this operation all other ECM
functions remain as normal.

The ECM operates immobilisation in three states:

'New.'
'Secure'.
'No Code'.

When an ECM is unconfigured it will operate in the 'New' state. When an unconfigured ECM is installed the engine
can be started and operated once only, then the ECM has to be re-configured to either 'secure' or 'no code'
configuration depending on whether a security system is fitted to the vehicle. This is achieved by using TestBook.

With the ECM in a 'Secure' state, it will not function unless an alarm system is fitted to the vehicle. A 'Secure' ECM
cannot be configured into a 'No Code' ECM.

With the ECM in a 'No Code' state, it does not require an alarm system to be fitted to allow the engine to operate. If
the ECM senses that an alarm system is fitted it will not start. A 'No Code' ECM can be configured to a 'Secure' ECM
using TestBook. A 'Secure' ECM can not be configured to a 'No Code' state.

Setting up of the ECM immobilisation configurations can only be performed using TestBook.

If a vehicle stalls immediately after starting it is possible that it has been immobilised. This means either:

The ECM was configured as 'No Code' but the ECM is receiving a code at its alarm input pin.
The ECM received an incorrect code.
The ECM was expecting a security code but did not receive one at its alarm input pin.

Nanocom does not appear have any means of changing the state of the ECM from Secure (Robust) to No Code (Non-Robust). The Hawkeye may be able to do this, as the docs make reference to enabling/disabling immobiliser.

thanks, great info however im a little confused (but will run the info by my landy guru). he will know what all that means! hes quoted me 250 to bypass the immo and alarm, so at least its cheaper than 400 for new keys.

I have to ring the LR dealers in the morning and will ask them if having new keys programmed will solve the alarm problem. It may be better to have a new set of keys cut so I still have the central locking, but I'm worried about the alarm still going off.

(the door locks didn't pop up all the way when using the fob, so you had to insert the key and open the door manually. this would set off the alarm until you put the keys in the ignition and turned on the ignition lights). I did have the locksmith repair the barrel as the key was akward to turn correctly to enter the EKA code. Now its working fine but you need to try the code a few times to get it to work properly.

thanks for all the input guys- and great site!.

On a side note you can get keys from the UK for about $135 (AUD). Another $40 - $60 to programme and $5 to cut it. Postage about $12.

If you know someone with a nanocom save $40 - $60

Andrew

thanks Andy, normally I would do that (currently doing it with a Ducati motorcycle I bought from the auctions in Sydney that came with no keys. just sent the ECU and they will program new keys for 200 pounds).

I did hear that some overseas key fobs run on a different frequency so cant be programmed when you get them here. (my locksmith told me this). my main concern is the hurry as I need them straight away.

thanks for the advice anyway mate....

**Andrew D** · 3rd March 2012, 03:59 PM

Like I said it's a side note. I understand you have more pressing issues at the moment. By the way your locksmith is not entirely correct and I would say wrong. Generally there are only two to choose from (4 all up). This can usually be determined from your VIN. As long as the frequency is right either of the keys will most likely work. Did for me.
