Hi. If the vehicle was starting before you replaced the ignition switch then the switch may be defective or the switch may not be lined up properly. It is not uncommon for the security system to act up after an ignition switch replacement, depending on what was done. You should enlist the help of a certified mechanic, like one from YourMechanic, who can inspect your car's starting system.
