car child locks?

[x6bec]

Can you get children's car locks to stop kids opening doors from inside? My car hasn't got them built in. I remember when I was a kid my parents had them?
Thanks

most modern cars have a little button on the door. if you open the back passenger doors where the button bit is that goes into the hinge is a little switch. you can switch this up/down and then the door can only be opened from the outside so that kids cant then open the door whilst you are driving. Have a look at your manual or find one online and see if your doors have this button.

If it is a old car it is a little switch on each of the back doors.
open the door and have a look on the bit of the door where it catches when it closes there will be a little slidy switch
