Replacing 172 alarm keys

[Rob_Willow]

Hi. My 2003 clio 172 has a 'sigma' alarm fitted. However the alarm plip key i have for it is broken. I need to replace the alarm fob, and want to know if a replacement alarm key fob from ebay could be re programmed, or are they only programmable to one vehicle, like the main ignition key for the car?

I was looking at this one: http://cgi.ebay.co.uk/sigma-car-ala...ameZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting


thanks

You can program the key yourself if you have the red emergency by-pass key.
If not, you need the CP1 programmer.
Its a box with a lead that pushes on to the LED and accesses the program.

Any BMW/Renault/Subaru dealer will have one as Will a Sigma dealer.

I've got a keypad above the windscreen, which according to the instructions allows multiple keys to be entered using the security 4 digit code. However it doesn’t state whether or not a used key would work. I presume if I got a new alarm key, it would be fine.

You need to check with the supplier that it is a Renault compatible remote. As some were made specifically for BMW and have a different rolling code algorithm.
