Why won't my car doors unlock or lock properly?
Car doors fail to respond to electronic controls, forcing drivers to rely entirely on manual keys while leaving the vehicle vulnerable to accidental unlatching or break-ins. This electrical malfunction disrupts normal operation, leaving key fobs unable to secure the vehicle and causing security risks.
