hi belz,is actually an after market alarm system..
i went to accessories shop, and they told me the alarm can't be duplicate and is no more in the market already...
normally cobra systems can be duplicated. we have no problem with reprogramming or duplicating keys or remote for cobra so far. perhaps it may be easier if you can let us know the year and model of the device. alternatively, you can visit our shop and we can check for you.
