QUESTION: Hi,<br /><br />How can I make sure this transmitter will be working for my garage opener? I do have an overhead garage system.<br /><br />Thanks by sultan s 5/7/2014
STAFF ANSWER: You need to look at the back of current transmitter. IF it says 340Mhz then this is the one for you. Also open the current remote and look for 9 switches. So it needs to be 340Mhz with 9 Dip switches. Call us with a current remote in hand and we will help you identify it and we will inform you of the compatible accessories such as a key chain remote. by Matthew O a
