Hi there. Replacing your vehicle’s battery, should not have affected the vehicle’s security system operation. Assuming there was nothing shorted, during the battery replacement, would rule out a fuse related problem. This may require a scanner to access the vehicle’s computer(s) to diagnose. No spark could be caused by a faulty crankshaft position sensor. Accessing the vehicle’s computer for codes, may help lead you in the direction of repair. I recommend having your vehicle’s no start condition be diagnosed and repaired by certified technician from YourMechanic.
