you mean the coin door on the driver side?
Like don posted.
if it is the coin door and if the stubs are gone? a paper clip, dikes, a needle nose, a lighter. Do a McGyver on it. before Don's time!
using glue will not work. but if the stubs are gone you'll make new ones by implanting your own, then use JB welding 8640 let dry. the stubs on the side must be exact or it will be much harder to open.
go the other route till the velcro peals off, use a stronger, heavy duty Velcro. but clean ALL the oils off, you'll have to sand the pores and oil out of the plastic and use 90-07% ISo.... Alcohol. not alcohol. use less grade is like the oil discussion Lol
