Locked keys in car. What would you do?

OP, rather than going back to the shop, i think i'd have asked a fellow shopper to use their phone.
most have smart phones, so you could look up the RAC and take it from there.

Re:
Someone else's key opened my car

A couple of years ago I parked in a big car park in the center of town.
Someone was with me and we both had only a couple of quick jobs to do.
We hopped out, I locked up and when finished shopping I was first back to the car so put my stuff in the boot and got in the driver's seat.
After about 20 minutes I wondered what was holding them up and, looking round, noticed a few strange items on the back seat... 😬

Yes! I'd been sitting in someone else's car all that time.
😱

Sheepishly (but rapidly) I got out and took my shopping out of the boot... and saw, just a few cars along, my passenger waiting patiently, next to MY car.

Someone else's key opened my car!

That was years ago before keys were programmed.

Years ago, we had a Ford Cortina that we could unlock with a 2 pence piece

It was just very lucky that he happened to park outside the same shops!

Thanks for your really ingenious replies. My RAC documents were of course in the car and I didn’t know their number. It just made me feel very vulnerable although thankfully not for too long.

My car has an app so I can remotely lock/unlock my car from my phone.
I recently locked my keys in the car but fortunately had my phone.

Mine once managed to lock itself back in the 80s at 5am when I ran into a local newsagents and left the engine running. There was a policeman inside who told me not to watch, took some of the plastic type tape that was wrapped around the newspapers and opened the door in seconds.

Many years ago I left the dog in the car while I locked the front door. The keys were in the ignition, the dog jumped up on the door and pushed the door lock button down. Remember those? I’d been about to take the dog to my parents for the day while we had some work done on the house. What did I do? Phoned my Dad who turned up with a piece of wire and proceeded to unlock the door, he then removed the dog, told me not to be so daft again and drove off with the dog in his car Those were the days!

This reminds me of locking myself out of DH’s car - I think a Ford Cortina Estate. Must’ve been the early 70’s and I was
going to a birthday party.
I rang the breakdown people, describing where I was. ‘How will we recognise you’ asked the call centre. ‘Well’ I replied ‘I’m the only one here dressed as a nun!’
Yes, it was a fancy dress party.

Yes, I would call the breakdown services.

I am very careful about always putting my keys in my pocket or hanging froma finger because, like Witzend I once had a car that had a habit of locking itself.

I'd call the RAC too

My car once managed to lock itself - with my bag and keys inside - when I was at the council tip!
I called the AA or RAC, or whoever we were with at the time, and the nice chap got it open with no damage.
He said he’d known it to happen before with that car - a Ford Focus.

My phone lives in my back pocket, or on the rare occasion when I’m not wearing jeans, chinos or shorts, down my bra.
Tricky for you, if no one had answered then the window I suppose unless you have breakdown cover.

I always wear/a cross body bag when out shopping, no danger of leaving the bag anywhere.

But when MzOops car decided to lock itself with her key in the ignition and the dog in the boot on a really hot day, we had to break the side window.
