To program sentry remote controls for gates, one must make sure all of the software is compatible with each other. One must also make sure the programs support each other.
If the key has the built in remote buttons, it has sentry key.
The remote sentry is a 12-point support strike chain that appears in call of duty: modern warfare 3. It is similar to the sentry gun of previous games, but manually operated with a slower firing rate. This type of sentry gun is less noticeable in a few multiplayer levels because of its slightly smaller size. While using the remote sentry, the camera turns infrared as people are colored white.
