My electronic door opener does not open or lock the doors. I have to us the key

Last question first: No, there is no fluid sensor that prevents the engine from starting. This does sound like a concern with the factory keyless entry and antitheft system. It is difficult to know what is happening to the controls without use of a diagnostic tool for the body / electrical components that will be able to see what is happening. Unlocking the driver's door with the key alone should deactivate any antitheft system, and turning the key in the ignition should also. If there is an aftermarket system added to the vehicle, would strongly recommend this be disabled. I'm sorry to say you'll need to get professional assistance.
