Rover 800 820 825 827 Alarm Remote Controls.
Remotes, Remote Controls, Remote Key Fobs, plippers, zappers, call em what you like! ...they're all the same thing... ...or are they?
There are two types of remote controls used on Rover 800 Mk2's. The earlier Mk2 Rover 800's use Infra-Red (IR) remote controls and the later 96-99 cars use the much more secure Radio Frequency (RF) remote controls. Both the IR and RF alarm systems, use remote controls with two buttons and an LED which lights up both green and red! You can tell them apart though because the earlier IR remotes have a small IR eye on the front edge of the remote control.
I do not have much knowledge of the earlier IR system, but it seems that the IR signal can be very easily caught by those programmable TV remote control watches, and then used to disarm the vehicle! The later RF system appears to use a much more complex rolling code system, which changes the code with each use, making the vehicles much harder to steal!
On this page I am dealing with the later more secure RF remotes fitted to the late model 96-99 cars (and they are a bit complex so some of the info I have gathered on this page may not be quite correct!).
The problem with the RF remotes is that the extra security means that if you have a problem with a remote control (or if a remote is lost), it can become useless to you, and they can be an expensive problem to sort out! (try the fixes found on this page first!).
The alarm/immobiliser comes with an Emergency Key Access (EKA) Code which can override the system by using the Key in the drivers door lock to enter the 4-digit EKA Code. This should disable the immobiliser until the remote is next used to lock the vehicle. (see here; How to bypass immobiliser using EKA Code
If you have a spare remote that is not working (BUT HAS PREVIOUSLY WORKED WITH THE CAR), then pressing the unlock button at least 4/5 times in quick succession will sometimes re-sync them (or was it the lock, button, I can't quite remember!!!, but I have got remotes to work again that way on a few rovers.)(Also I can't remember if the ignition was on or off when I used to try to re-sync them, so try each button with the ignition on and off, it has worked on a few Rovers for me, and hopefully it will work for you too!)
Things are not as easy when it comes to adding a NEW or SECOND HAND remotes though!.....
Second hand remotes sold on ebay or elsewhere are of no use except if you need the buttons or the case to replace your older/worse ones!
The prices achieved for the remotes are high simply because it's a case of supply and demand, and although demand is high enough to drive prices up and keep them up, buyers just end up with a non-working remote which they chuck in the cupboard thinking one day they will get it programmed to the car, but this never happens because it's not as easy and straightforward as that.
The late model 800's will accept 4 remote controls being programmed to the car. The trouble is that not only do you require a programming device to do this, but all of the remotes you want to program to the car must be present at the time!
Even this does not seem too bad as people think 'ok, I'll get them programmed', but you also need the 'BARCODE LABEL' for each and every remote! (and very few owners have kept/passed these on with ownership!)
Without the barcode labels a remote can not be added, even if you have a new remote complete with the barcode label, unless you also have the barcode label for your old remote, your old remote will be lost at the reprogramming stage. So the new one simply becomes a replacement rather than an additional one because the old one will be of no use now!
If you just need the buttons/case though, rather than pay silly money, there is someone on ebay usually listing new ones of these for around a fiver.
but in general, if you only have 1 remote for your Rover 800, without shelling out loads of money, then it usually stays that way. (unless you buy a remote receiver with remotes already programmed to it from a scrap car and change the lot, but even then you can't be 100% sure that all the remotes with a scrap car were programmed in, and not simply ones from someones cupboard draw!!!! unless they were checked prior to removal.)(not sure, but you may also be required to swap the main ECU too!)
We have just 1 remote on the 820 Fastback, and if that was ever to go wrong, rather than adding a new remote, I think we would just bypass the whole thing and just fit a Thatcham 1 alarm/immobiser for the money instead (but keeping the lazy locking feature!), and reducing insurance premiums along the way!

If the IR remote stops working then it will usually require 2 x CR2016 Batteries.
(Handy Hint! Always write the date on batteries when you fit them!)
If the IR remote works some but not all of the time and you are having difficulty when pressing the buttons, then as well as cleaning the buttons/case/circuit board and contacts, try a small fold of Weetabix box placed around the circuit board at the top end, it usually does the trick!
Not sure why, but I always seem to use Weetabix boxes to do this!
