Safety Buckle Pro Seatbelt Lock and Seat Belt Locking Clip - Keep Children in car seat locked and tight – Stop Kids with special needs from unbuckle - Strong ABS Plastic Buckle Guard – Universal Fit

This is probably my best amazon purchase yet. I have a five year old that keeps unbuckling his seatbelt when he doesn’t want to leave a place. This is super easy to use. I can quickly get it on and buckled before he realizes it. Then I just tell my kid that it can’t come off until I turn the car off and use the car key. Which the car key fits perfectly in the gap to unbuckle the seatbelt.

I actually bought this for my mother who has Alzheimer’s and it works perfect she was doing the same as a very active young toddler might with taking the seatbelt off (while I was driving) I kept pulling over to the side of the road to put it back on and she would snatch it out again so this solved that issue and safety is of no concern now! Easy to use no gimmicks easy to takeoff!
