With your 182 you should definitely have an Alarm Manual for the Cobra (Renault-branded) alarm, and also a small certificate showing when the alarm was installed (and tested, in my case).
This should have come with the other paperwork in the grey pouch supplied with your car - if you don't have one, your dealer should be able to sort this for you; although the 'certificate' I have appears to be the "original" one, rather than a photocopy - so unless they keep a copy somewhere....
