Info for those who may not be aware - Newer cars must have an escape latch inside the trunk. I don't know when it started but my cars are 2005 and 2011 and both have the escape latch.
I have locked my children and grand children in the trunk (one at a time) after showing them the opener on the inside and had them unlock it themselves. Not one of them had a problem getting out.
I also cautioned them that different cars might be slightly different but it's there and to not jump out of a car that's fast moving - wait until it is going slowly or stopped at a stop sign, then jump and run like your life depended on it.
Then I pray they will never have need of the knowledge I gave them.
Excellant to know. thanks for this information!!
