ANSWER: My garage door opener is Precision Brand and my Marantec garage door opener works with it. by Celeste H a
ANSWER: i think it depends on the frequency of your opener. if it is 433.92 MHz it should work. i would suggest you call or email Marantec directly to confirm. I found their customer service excellent and they don't care where you buy from. by Frank C a
QUESTION: is this product works for all Marantec garage door motors? by Wei W 7/28/2013
STAFF ANSWER: THis will only work on marantec and precision brand doors that are 433.92Mhz. This same remote is available in the more common 315Mhz. Your unit hanging in the garage will have the frequency listed. Or one of your current remotes will have the 315 or 433 mhz printed on the back. by Matthew O a
ANSWER: No. They need to be the same frequency. by B K a
ANSWER: i don't think it works for "all" Marantec doors. You have to match the correct MHz. For my specific 433.92 MHz opener this remote worked perfectly and was easy to set up. I would suggest calling or emailing Marantec directly to answer your question. For me they were very helpful but I ultimately bought the remote from North Shore since they had a better price. by Frank C a
