Fireteach,

You may have fixed or found the fix but I want to share my experience today on a possible fix to locking your tonneau cover. There are 3 bolts holding the case cover lock, this is the mechanism you manually unlock/lock the tonneau cover with the factory tool/thin 10 mm wrench. That mechanism is adjustable. The brackets for the bolts are slotted.

I replaced all 7 hydraulic cylinders through Top Hydraulics. Guaranteed for life. Great company! This case cover lock (it’s heavy) was installed by me and I just let it hang down when I bolted it back on. Turns out the tonneau cover would not lock. It looked closed but was not locked down. This prevented the top from coming down, opening up. If I put the top down manually, the top would cycle completely up as factory.

By the way I’m doing this with the car running to avoid any electrical drain on the battery.

I hope my experience helps you.
