Locked Out:

Yes, I did it. I successfully locked myself out of the car. I was visiting my dad's bro and had to retrieve something from the boot. I clicked the boot open button on the remote, opened the boot, put the key inside and took out the bag I wanted to take, and then closed the boot lid - without retrieving the key

For the next 10 minutes, I gave a stiff competition to a headless chicken (or so they say). Once initial panic set in, we started trying different ways to unlock the car without the key. There is no gap between the window sill and glass, so could not try inserting a scale or some other object to unlock the car. I made a call to the Tata customer care and they coordinated with the nearest service center and said I will get a call from the TASS and they will send someone to my location in the next couple of hours.

It was then we remembered that I did something similar years back (pocketed the key of my dad's bro's car after parking it and came back to Bangalore with the key in my pocket - the spare key was inside the car) and we managed to open the car using a mobile phone. By this time, dad managed to get hold of a relative who works in TASS and he also suggested giving the mobile phone route a try.

I called up my friend who is in Bangalore (who, fortunately, had my house key with him) and he took the spare key from my house and after putting his mobile on speaker, unlocked the car couple of times. I also put my phone on speaker and kept the phone near the front door and voila, after a couple of times my friend clicked the unlock key, we heard the sweet music of the car unlocking

Heard about this hack several times but this is the first time hearing from a verified source and happy that it works. By any chance can you capture this again in a video and post in youtube? will be helpful for many.

Re getting locked out of the car. Damn. That's a nightmare. But this is the first time I've heard of the workaround you did to get it unlocked! Sounds interesting. The 5th Gen City has a tech whereby even if you put your keys inside the boot and close the boot accidentally, it doesn't close, and gives out a warning sound indicating that the keys are in the boot. It's a very commendable piece of tech and more car makers should make this available, instead of the standard gimmicks we get in the name of technology.

+1 on the video regarding the Locked-out instance.

Would be great if you can capture this on a video and post it. I always rubbed this off assuming it would not work.

But hearing from a verified source on TeamBHP is reassuring and this would truly be a time saving hack.

Thanks,
Nishith

Slightly off topic ...
My Honda city wont lock itself if the key is inside . One day we packed the spare key inside one of the suitcases and when we tried to lock the boot it kept unlocking. Finally i had to take the key out and then lock.

Both Tata and Mahindra have achieved design parity and better safety compared to other leading makers. Now is the time to focus on these minute topics for a wholesome experience.

Sure Dev, I will capture it on a video.

Thanks, BrakeDancer. It is a nifty feature and I am happy to know that City has this.

My Punto also has a feature like this - all electricals get switched off after 1 hour of locking the car. So, even if you leave a light on accidentally, you will not drain your battery.

Wish all manufacturers incorporated features like these.

Thank you Nishith. I will sure make a video and will post it.

Wow, that is really good. Wish these kinds of features were standard across all models.

Unlocking a car using a distant keyfob and two mobile phones through radio signal - posts copied to a new thread.

[PreludeSH]

Really ? Does the keyfob emit frequencies that match the human frequency range ? Even then only a small band in the human voice frequency is passed by modulating to the radio frequencies and converting back to what was originally passed. If the keyfob is using higher radio frequencies, it cant work

If its working, you can as well record the tone and play it back to unlock

+1. I thought it was a thing of the past with these modern key fobs. For example in my XL6, if you keep the fob inside and press the lock request switch on door handle, it emits a long chime and won't lock itself. Even if you use second fob to deliberately lock the primary fob inside, it won't happen.

Trust Tata to not offer something this simple in a 20+L car. My i20 also gets this. I am sure almost every other car in the market does.

Also, since you have the Harrier, does it not come with iRA? Most connected car apps including Bluelink and iRA allow you to lock and unlock the car via the smartphone app? Why couldn't the app be used to unlock the car?

In harrier/Tata there is a separate button which unlocks only the boot. If you use that button the 4 doors remain in lock position and just the hatch door is unlocked.

In this case the OP used this button just to unlock the boot and forgot the key inside the boot.

If you leave the key inside the passenger compartment/dashboard etc. the Car does not lock itself even if attempted deliberately.

[whitewing]

It boggles the mind that a mobile phone audio mic and a mobile phone speaker was able to pick up and replay frequencies in the ISM radio band ranges which is in the MHz ranges.

There ought to be another explanation.

That is interesting and quite reassuring that this trick indeed works. Though I have heard from many, I feel that I can trust this now. I still pray that I would not land into this issue anytime in future. Thanks Anoop for the share. Also, as requested by others please post a video of the same so that it will of great help.

I don’t trust the internet very much, but I trust it on this one:

You might get lucky, but I would not rely on it. Any reasonable modern car, not a chance! It would also depend on what kind of mobile phone and kind of mobile technology you would be using.

Same thing in my 2017 S cross as well, the car won't lock with the key inside, I ws under the impression all cars get this.
