Original remote information: 2-Button 310mhz transmitter for most older S Series Marksman alarm systems: S310, S410, S510, SA-550M, S312, S412, S457, S557, S657. This is a scratch code remote meaning that rather than program the system to accept remotes, the remotes' circuit boards are permanently altered with cuts on certain connections which result in the code your system is expecting.
We're selling the replacement shown. The way this works is that after you make the purchase we'll email you instructions to send us your working remote. When we receive the working remote we will clone it's codes and put them onto the replacement shown above. Then we'll send your remote back to you with the clone replacement. The new remote will work on your system exactly the way your working remote does. The reason is because it will have exactly the same codes and your system will think it is the original working remote you had sent us to clone.
IF YOU DO NOT HAVE A REMOTE THAT WORKS WELL THEN DO NOT BUY THIS LISTING. IF YOUR REMOTE HAS A SIGNAL ISSUE, THE CLONE WILL HAVE THE SAME ISSUE.
