Hi i have a Renault Laguna x reg old shape and i cant open bonnet with lever or manually can any1 HELP!!!?

If the cables are broken the only way to open the latch is to drill it out. Check to see if you can access the latch under the hood, or you may have to drill through the bonnet. Once the latch is open you should install hood pins like on racecars to keep your bonnet closed.
