alarm keeps going off
 
The truck is acting really weird.
Alarm keeps going off without even locking the truck.
Also the light on the key started to blink rapidly.
Any ideas? Neighbors are not happy!!!:eek:

Try taking the battery out of your remote and see if that helps. On mine the unlock button on the remote was stuck on somehow causing my truck to keep unlocking and lights coming on. The LED on the remote lights to show a signal is being sent.

Had exactly the same on my 2000 V8 HSE about 14 years ago whilst on holiday in France. Sometimes it's an LR computer glitch and sometimes local EMF or mobile phone signal interference, usually your own phone in the truck. Disconnect the battery for 30 minutes minimum or alternatively get a good quality code reader and find the system problem codes.

Even my TD5 still occasionally acts up so I turn off the phone, get out and lock up the truck, wait 3 minutes then open it again and bingo all's well and ready to go. The worst areas seem to be outside X-ray suites in hospitals which are well known for screwing up remote systems due to heavy EMF.

PS wtf is god by the way? Another mythical figure I assume.

My hood switch got boogered once and cause the alarm to go off randomly. Apparently the truck thought it was being stolen. If memory serves it is on the driver side you might just punch it to make sure it is operating smoothly.

My neighbors already hate me because I have a rover that is constantly being repaired. Haha. I don't care what they think.

RawFaith 03-28-2016 03:24 PM

wow!
thanks for the replies, for some reason my phone wasn't getting notifications .
Disconnected the battery that night and just reconnected, will try today how does it work.
looking on eBay for another key, anything in particular that we need to look for? Is it just as simple as getting a key and going to a locksmith?

This are just the cases. A trick. New keys with electronics in them are over a hundred.

A locksmith can make the key. But I haven't found one that can program the remote. The programming is done from the truck end with a computer. If I'm wrong about that I'd love to know it. I haven't had a remote key for years.

Honestly we don't even use the "remote key" as it self, just lock and unlock manually.
Now, our keys don't have a chip? ( inside that connects of to the computer of the truck to get it started?)

Nope. The only thing electrickery in the fobs is the central locking. Nothing that talks to a computer or anything.

It's as simple as a key blade with some notches cut out of it.

Almost sounds like you have faulty horn buttons. Seen horn buttons cause the horn to go off randomly and sometimes stick on.

hmmm didn't think about that one....but the lights going off?? I'm almost positive is the alarm.

So far no issues YET!!!

Will try to pull the battery out of the key. when we got the truck only the locking bottom was working so we never messed with it...:D

No. The keys don't have a chip. A plain old metal key will do the job. That's what I use.

The remote keys just signal the alarm system to arm or disarm and lock or unlock the doors.

Sorry... Just saw I was a Johnny come lately.

BritishautoworksSD 03-28-2016 09:27 PM

Any Land Rover shop with an Autologic or T4 can see the alarm trigger history. The body control unit stores this information and is very helpful. Maybe worth a diagnostic fee for this info

The remote keys just signal the alarm system to arm or disarm and lock or unlock the doors.
The alarm system is a bit more complex than suggested and you must be some of the fortunate ones blessed by the Rover Gods. Some folks haven't been so lucky because the remotes do/can interface with the BCU for mobilisation to allow starting. The BCU has many programmable options to en/disable many of the anti-theft system options.


Handset and receiver
The handset is incorporated in the key. It uses coded radio frequency signals to lock, unlock and super lock the vehicle
remotely with a range of up to 10 metres (33 ft). The handset also mobilises the vehicle by transmitting a
remobilisation signal when the handset is within range of the passive remobilisation exciter coil.

Passive remobilisation exciter coil
The passive remobilisation exciter coil consists of a coil around the steering column lock. The coil energises to create
a magnetic field when the ignition is switched to position II.
This coil activates the handset initiating the mobilisation of the vehicle.
Input/Output
The input to the passive remobilisation exciter coil from the BCU is a 12 volts 125 kHz sinewave. The passive
remobilisation exciter coil also receives an ignition controlled power supply via fuse 20 (15 amperes) located in the
engine compartment fuse box. On receiving these signals, a magnetic field is generated which activates the handset
to produce a remobilisation signal. This remobilisation signal is transmitted to the remote receiver and onto the BCU
to allow the engine to start.

Good grief I didn't know it did all that. I just get excited when mine unlocks and doesn't start honking.

Not having a remote (that is programmed) I do live in fear of a superlock event.

When I had a broken driver door handle I was able to arm and disarm, lock and unlock, all with a screwdriver (I remember clearly because I locked myself out and armed the alarm, both inadvertently) in the middle of the fix. Also, when I accidentally locked and activated the alarm, causing the horn to honk, I was able to deactivate it with the screwdriver.

RawFaith 03-29-2016 08:39 AM

Geeeee
I'm freaking out now!
How much will the stealership want for a key !?

mollusc 03-29-2016 09:58 AM

I don't have a remote fob at all. My alarm works when I lock and unlock the driver's door with one of these: 2 Land Rover Discovery Range Rover Key Blanks 89 04 | eBay

hmmm ...
interesting facts, actually just got a knee injury and had been to some labs and hospitals between x-rays, MRIs and physical therapy....perhaps have something to do....but why when getting home?

PS: What is GOD? that is a very good question, if that is an intellectually honest one in the pursuit of true. BTW assumptions can be very dangerous...

I guess at this point just need to order some and give it a try....:eek:
thanks

CWE100710KIT- Discovery Series Key Remote (Non-SLABS) MSRP $224 plus programming

You will need an Autologic or T4 to program the key remote.

BS50MGSXR 03-29-2016 08:41 PM

maybe this is an option? iv not gone this rout my self. but thought it was another alternative to dealership.

Remote Key Europe Land Rover Discovery Series 2 - 1999 to 2006 Key Repair Kit - Remote Key Europe


i do the manual un lock, lock but a recent pin broke in the door lock at walmart locking me out of the car. so i think having a alternate lock/ unlock with the key fob is looking like a better and better idea. I am thinking of buying a Nanocom and just program my own key fobs to the vehicle. $350, but to do multiple keys, and also other scan options are kinda neat as well.

The problems I encountered at a hospital were exactly as the tow guy said, he moved my truck away from the MRI and X-ray area and it immediately opened on the fob and then started. He said it wasn't the first punter who has experienced problems exactly where I was forced to park in an emergency.

On other occasions it is either an LR software glitch or my own mobile phone and signal direction but on every occasion we have got out of the truck, locked it, waited awhile, opened it again on the fob and bingo it started OK. Oh, I also switched my mobile phone off first.

As for God and religion, a short explanation. I was brought up amidst both catholic and jewish parentage and families. It was a nightmare :eek: Having seen all the international discord caused by religions for 60 years I then decided back then atheism was my only option and thats the way I've been ever since. I am totally tolerant of others faiths and religions if they are peaceful and not enforced on others, but as whatever religion goes, I cannot subscribe myself. It's wasn't a blase comment but an intellectual and committed question but slightly tongue in cheek.

I think Paul Grant fully understands my position on this one.
