Cant get into landrover fob not switching alarm and emobliser off bought new reciever still not working

IMMO lamp glowing in UNHAPPY STATE SURE>
FOB H3LL been there too many times.
first off the fob batteries must be good. inside fob.
battery put in backwards has no chance ever.
never have just one working fob key on any car
or land here. x
off to the locksmith you go or they to you.
my fobs died here about 8 years old (new to now)
2 new once died, here just last week, 8 years old
1st the bottom switches inside gold wore off. dead.
no cure ever for that, !
2nd fob when berserk and has unlock command transmitted endlessly and its switch is shorted for ever. no fix for that. again.
and all failed every year for coin cell. every one.
never have just 1, or costs can go super high.
mine cost me $75 to make 3 new keys.(programmed)
(had new keys in hand me)
that is my advice, and how to be proactive

retry replacing battery new doesnt mean cant be defective if it is good than fob needs a relearn different cars have different relearn that you can perform but if the fob has other features such as start that will have to be done at dealer ----

Check to see if your vehicle honks when you press the "lock" button on your key fob. Press the "lock" button multiple times in a row. Many devices won't beep unless you double-tap the button after locking. If the horn doesn't honk, but the lights flash, your chirp feature is probably disabled.

Use your keyless fob and ignition key to enable the audible chirp. The process varies considerably on different makes and models. You must usually consult your owner's manual, a dealership or the alarm manufacturer for the correct process.

model not stated but i would hazard a guess and say you have a problem with the reciever unit in the vehicle ,if you had a spare fob to eliminate this as well it would help as maybe no signal then it will not operate the internal manual switch although i do doubt this but? - Now the locking mechanism is controlled by the reciever that sends a signal to the relay to operate the locks so i expect this to be a seperate unit from the ECU but it could be incorperated then a current is passed to the operating relay under the dash which in most vehicles operates the relay directly but some more modern cars this just send a current via the reciever which could again be incorperated into the ECU .If i had car in front of me with the bonnet up and my automotive multimeter in my hand i would soon determine as to what type of system but weither i could repair it without a lot of expensive new parts is another question .

if its a replacemet fob it can only be done with diagnostic equipment
if its the original fob you need to de-activate the alarm system with a 4 digit code from the vehicles security card, I cant recall how to do it but details are in the owner's hand book. once the alarm is dissabled you need to hold the fob close to the vehicle and press either of the buttons on the fob 4 times or more in quick succession.

need to find out if key has a electronic chip in it if no chip any place that carries the blank can cut u a key most key cutter places have the test box to verify if it has one --dealers and a limited few lock smiths[check ur local area]can cut ur electronic key ----

try changing the fob battery .the freelander has a fob low battery warning tone that will start after the alarm has been deactivated by the fob with a low battery and will stop after the key is switched to acc. for any one wanting info on problems with freelander , goto this web site . http://www.myfreelander.co.uk/

if it is a mems unit , it will need to be programed to the key fob and alarm . (there is no way round it).

first thing i would be checking is the door switches on each door if are broken or by removing switches to see if connection is broken or badly corroded also check bonnet & tailgate switches for same problem.

You need to get one that works on the same wide range frequency as the reciever in the car, and then it's a simple matter of opening both the new and old fobs, and matching the fine frequency settings by putting the little switches inside where they should be according to the old fob's switches. If there are no switches in the old fob, it's preset and there's not much you can do about it.
