Remote Locking Broken but Alarm Ok

[balanloan]

My Dads G reg 190 has a problem

The Scorpion remote opertates the alarm but not the central locking

Can anyone help please

Try this

Hold the button down for 4/5 seconds, EDIT: press fob button briefly twice.
Within 30 sec or less, put key in ingnition, and turn to position 2.

 

[balanloan]

Tried that but no success.

Does the door key opperate the central locking, or just the drivers door.

 

[balanloan]

It operates all the doors

 

[pascal]

Oops sorry,

Miss wrote it,
Should have read. Press either fob buttons briefly TWICE and then put key in ignition, and turn to position '2'.

 

[balanloan]

pardon the ignorance but just to check. Is position 2 the one where the warning lights on the dash light up?

 

[pascal]

Sure is my friend. but don't turn it to start. LOL

 

[pascal]

PS. Have you a 1, 2, or 3 button fob.

 

[balanloan]

The Fob in this case is a Scorpion Fob with only one button is that standard as opposed to a mercedes brand?

 

[pascal]

Did you try it by double pressing the button.

 

[balanloan]

Yes but no success. The alarm sets itself but no luck with central locking.
Apparently the problem started after he had a problem with his battery

 

[pascal]

Its a pretty straight forward system. Two wires from the Scorpion alarm interupt the Central locking control wire (as far as I know).

Pascal.

Will check some other scorpion data I have, later.

In the mean time try the above method again. And if you have a reset key for the alarm, reset that first.

 

[balanloan]

Thanks. Will dig out the alarm reset info

Better still, If you obtain the number of the alarm (ie 915 or 838 etc), I can fill you in with more info. Scorpion 838 (single CC wire control) was fitted to early MBs
