purchased to replace the lock switch system of the 1998 Renault Laguna Nevada which is very unstable, I do not regret my purchase. First, the current price is ridiculously low for a product of this quality and this finish (especially remote controls). Of course, it is necessary to have some knowledge in electricity, but the result is perfect. I installed in the housing of the control box near the warning handbrake, or one finds all control son doors / trunk and flashing. Furthermore the remote control max distance is very good.
