Tabs inside of the keyless remote slot become worn, stick back and/or break . in addition to being costly to replace, it poses as a security hazard or a high risk for theft because the car doors will not lock and alarm becomes disabled. the vehicle will think the key is still in the ignition. after researching this issue, i found that countless people have experienced this issue. this happened to my vehicle today. it should be noted that my vehicle was parked in a business parking lot when this happened.
