The DNT00027A Linear DT3 +1 remote replaces older model DT3+1 remote transmitters.
The DNT00027A remote will work with Linear garage door or gate operators that use 8 On/Off dip switches to set the code. This is a brand new remote that comes from a bulk purchase pack. This means that it is wrapped in a plastic bag with no box. It comes with visor clip, battery and programming instructions. Codes are set by matching the switches to a working remote or matching codes in the receivers.
When you match the number DNT00027A on your old remote the new DNT00027A is the correct replacement remote.
