I have a renault magane convertible and believe I can activate the cars alarm system when the roof is down. I do not know how to activate the alarm when the roof is down as I am missing those instructions from buying the car. If anyone knows what I have to do to activate it it would be a brilliant help...Thanks

If you have a keycard and not a normal key, you stop the engine and put the keycard in and out of the slot twice within 10 seconds of stopping the engine. This will de-activate the sensors. It does on my Laguna.

Hope this helps.
