flip key ? they are off the later cars and i'm sure they are different frequency and certainly a different coding system

if you could all the old bits inside it you'll be ok (*immob chip inc)

i'm sure theres a thread about it somewhere


as for recoding original key

1 - check batteries are at least 2.9v and NO LESS !!! and test your new ones too (not kidding)

2 - make sure your locking system works ok with the key in the first place as a broken or jammed solenoid can freeze the system full stop and you'll get nowhere

3 - try the programming with alternate buttons - hold lock press unlock or hold unlock press lock etc

4 - if all the above tried to no avail a friend with a same style remote is handy as they can be programmed to your car to test it and vice versa - just remember to recode it back to his/her's after ;)

some of them had the older system on and had to be coded like this.
complete the following within 1 minute!

put key in driver door lock (all windows closed)

turn to unlock position 3 times holding for approx 1/2 second each time & within 5 seconds! remove the key & observe the red led in the door flash

press & hold lock botton

whilst still pressing "lock" press & release "unlock" 3 times, the door LED & the key fob LED should now flash 5 times to indicate you were successful.

if you have another key, you must repeat from "press & hold lock button" & work fairly quickly (book says within 15 seconds for each key) if no second key then wait until door LED goes out & then try the remote key fob

I have tried this...

sit in car - doors closed

1 ignition on to red lights on dash
2 turn off immediately and pull key out
3 hold 1 of the buttons down (dont matter which)
4 PRESS the other 3 times ( with a SLIGHT pause) 1 . 2 . 3
5 watch led on key (should flash) and doors usually try lock/unlock
6 turn ignition key back on to red lights and wait 5 sec
7 key out again and test operation


but at stage 5 the doors do not try and lock/unlock

Can't get my central locking to work remotly :(
All doors are opened manually with the key, so that works.

:shrug:

Ive got the same problem with my kiwi cupra its annoying so bad because i only want to be a posh twat who unlocks his car 20 feet away just once.
all these turn off then turn back on for so many seconds are bull has it actually worked for anyone because i want to know

can show you on video if you want ?

works fine if the remote has good batteries and works and the central locking system is good

try a new or a different remote ? sounds like it needs one or something else is wrong

i get the led on the remote to flash 5 times but thats it.
the doors dont try to open or lock during the 7 steps either.
does anyone know when you press your remote to lock the car,should the red led on the remote stay on constant when holding the lock button as mine flashes when i hold the lock button on the remote?

my seat is 1999 and the remote didnt work when i got it. i thought it was the battery so a changed it over, still no luck. tryed adding an extra 0.4 volts on 2 it but still not luck. then tested my key at my dads garge-- the key wrked and was sending out a gd signal.

had 2 be the key code(i thought). got the key recode by seat glasgow £88 + vat. but still nuthing. it apperd i had a fulty recever unit and seat wanted anther £128 + vat to replace it. so ended up ripping out all the air locks, electrics, vacum pump and fitting central locking kit £22 from halfords.

the power in the keys seems to be a real problem and the cost if it ****s ups.

I've been having this problem too. I managed to code the key and it works intermittently so I will be testing the batteries using my (newly purchase!) voltage meter.....

Thanks for the other suggestion of how to code the central locking and I will give that a go tonight!!

Hello everybody!
I had the same problem with my cupra 2 '98...first thing that went wrong was locking mechanism on codriver's door- the stupid air "cylinder" or how can i call it, had a leak...i had to buy another one(second hand 30€, new costs 120€ at local dealer)...great, i installed it, try to lock it, everything worked fine, except of the remote...
I tried to solve the problem with all methods posted in this thread, and eventually i realised that i was doing something wrong->
according to first step by step recoding you should do exactly what it says->
1. turn egnition to red lights AND
2. then immidiately turn it off <- that is the important part
.
.
.

at first i waited for a couple of seconds before i turned it off(and then nothing happened if i hold down one and pressed another button for 3 times, except the led was flashing on remote) so make sure you are doing it right!

thanx a lot for this solution, F2 Ed. it really helped me:coolthumb

you can try it with any mk2 style remote by the way to test it just make sure if you borrow a mates that he codes it back to his car after :)

How do you do that? Surely if their key was different you wouldn't be able to do step 1.
1 ignition on to red lights on dash

Reason I ask is I've just bought a key off ebay but I think the blade is completely different to mine. Could I do this trick to check whether it's going to work before I start ripping my existing key apart?

Cheers

i believe that you can remove and dissasemble your original key to seperate central locking remote and key part-> so you can use someone else's remote(not the whole key). it's done in 10 seconds or less :)

awesome pic mate! am i right in thinking that the key splits into key/remote without actually opening it up? I can see how I'd do that with the remote one but not with my non-remote one.

ye the remote splits as for non remote the prcedure above is for coding the locking control not immobiliser mind :)
