My key remote is smash and car lock is there anyway i can by pass that and get car to start

Hello, sorry for all the health problems -- I would guess that it is not possible to bypass this, and that you'll need to repair your anti-theft remote concern. The only possible scenario you could maybe resolve is if the anti-theft system is not from Mercedes-Benz and not installed by the factory. In this case, an aftermarket alarm could be bypassed or removed to restore normal operation. A factory equipped alarm will not be able to be removed, however. Best to have someone near you with some know-how have a look to give you guidance.
