Keyless Entry Not Working.

[dannyjna]

Hello!

Ok so i bought my is220d on Saturday morning.

The fob and button on the door didn't work but the car has a separate fob fitted to work the central locking.

I checked the Battery in the key and it was the wrong one so I've fitted the correct Battery and now when i press the button on the door the key flashes as it should BUT doesn't open or lock etc.

Ive tried to add a new key but get no communication with the smart entry system, as if its been cut out for the fobs to be wired in any one else had this problem?

Does the fob work for starting the car (properly wirelessly, rather than holding the fob by the start button)?

Maybe the fob has not been coded correctly to the car, or maybe the drivers door lock has been changed - but actually that shouldn't make any difference. Does the mechanical key fit the door lock?

Do you have two key fobs or just the one?

Hi mate thanks for the reply,

Yea I don't have to hold the key to the switch it works wirelessly I only have 1 key at the moment and can't add a key as there is no communication with the Immo :(

The blade also Fits the door

Hmm - you may have a faulty fob - take it apart and examine it closely, especially where the buttons are 'under the skin'. Make sure everything is in the right place and there's no damage to solder etc - not that you can do much about that.

Do you have another key? (not linked?)

Might be worth re-linking the one you have partly working and any others. Need Techstream for that - Lexus dealer, or you can't be a million miles away from me - send me a pm and tell me where you are.

What do you mean that there is a separate fob fitted for the central locking?

It's got a key and now a fob that works the Central locking

[ChumpusRex]

Do you mean a separate non-lexus fob?

If so, it sounds like someone has cut the wires for the built-in central locking and redirected them to the add-on fob box.

Maybe the fob Battery ran out and someone didn't know how to change the Battery - so they changed the car's central locking.

This sounds weird.

If you are not too far away I'd take up John's offer and go see him for half an hour. He can walk you through what you should have as regards your key fobs.
