If you cannot activate the electronics because you have no remote or pin code, it is most likely the key cylinder will not be operating anything.
You need to bypass the motor and use the emergency release.
for info on how to do so....PM me.
The cylinder *is* the mechanical override. The cylinder doesn't do anything when it turns, but once it is open/picked you can pull it out of the door, and then pull the string attached to the back of the cylinder to disengage the powered opener. Then simply lif the door manually and roll it up.
That cylinder will open with gentle raking in a matter of seconds, I did one in an identical (albeit much larger) door earlier this week.
I have done these before as well. This is a very good description. Is the lock located at the top of the door? If it is on one side near the bottom it is probably a bolt latch that will not release the door. If it is in the middle, most likely towards the top, it is probably the opener release. These are, as stated, easy to pick wafer locks and pretty common. A new lock can usually be ordered from the door manufacturer with a key for $25 or $30. These are much easier to replace with two people although I have taped the bolts to the outside and carefully installed the nuts on the inside.
