I'm still researching the possibilities of installing a remote start in my '97 Disco 1. I'm getting conflicting reports from different manufacturers whether I need a "key box" to store a key inside the car to bypass the IMMOBILIZER anti-theft system. I'm told that I can buy a blank LR key and have it cut by any key shop WITHOUT having an onboard chip on the key programmed by Land Rover prior to use. Is this true? If the keys don't have a chip in them, there should be no need for an IMMOBILIZER bypass. Is the shop just trying to get me to spend extra money? I'm looking to have a Crimestopper FM 2-way system installed.

Has anyone out there had any luck with a remote starter on these vehicles?

Thanks.

I just had to buy a third key from LR at a cost of $140 CDN and then spend another $45 to get all three reprogrammed. They have to be done together at the same time apparently. This was done because I was told that they needed to rob a chip form one of the keys to be installed under the dash with the Remote Starter module. The rest of the key would then be garbage.

I was told i might be able to get a valet key that was cheaper, but the LR dealership said they were available for the Range Rover only. Now that they reprogrammed, One of the keys that worked before no longer works the alarm and locks, but still starts the vehicle. I don't understand why it still starts the vehicle when it is supposed to have an immobiliser. Perhaps the chip has different codes for the alarm and the immobiliser. Anyway, now I have to have them reprogrammed again as a set. The dealer is doign it for free but it's a pain as they are far away.

I just bought a fourth used key on ebay so I could store one on the vehicle. I figured the fact that the shaft is cut doesn't matter (the new one LR gave me isn't cut and it still works the doors). I recut the blank and use the ebay one to dismantle to ropb the chip. I'll just wait until the used key arrives before reprogramming them all as a set.

What I understand even less, is how they are going to make the Remote Starter work. Right now, I cannot leave the vehicle running and lock the doors. The horn beeps and it just won't work. Maybe it's a programming thing that needs to be done by the dealer.

What year is your Disco?? Mine is a Disco 1 - and Atlantic British has keys for $7.95 and they claim that they can be cut by any key shop with no programming required.

Thanks.

Update - I just talked to the local Land Rover dealer and he verified that the '97 Disco 1 does NOT have a transponder in the key - and that any local lock smith could copy your key onto a Land Rover blank.

Why then are installers saying that you need a transponder box? Extra profit?

The keys in older Discos 96-97 do not have chips in the keys. They do however have chips in the remotes. The ignition has a sensor that detects the remote (key fob) when it is in close proximity to it. In other words the remote needs to be on the key ring when inserted into the ignition so that the sensor in the ignition detects it.

I don't have a remote so I am never able to program my alarm or test it in any way. The only way I can arm the alarm is to use the key and then it is only passive (perimetric - meaning the doors and hood is protected from break in). If armed with the remote it is considered volumetric and the vehicle is passive and sonic protected (if there were movement or a loud sound inside the cabin - like glass breaking - it would sound).

As far as programming 96-97 needs a dealer to do it. Pre-96 can be done using a simple sequence of arming and disarming. LR must have figured out that this could make them some money I guess. Like the cost of the LR's in the first place doesn't do that....
