How to open our access panels and doors?
Usually we have budget lock ,push catch ,high security lock ,cam lock options for all our steel  access panels and steel access doors . Each access panel we supply keys for free which is packed  inside each package .
For aluminum plasterboard access panel ,it is push to open lock ,just push the lock ,it will be opened .
For plastic access panel ,it is quite easy ,just use a screwdriver to pen the door .
