In fact, when converting the regular to a fob key, you remove this chip from the Original remote and place it inside the Fob. Things become difficult if the OE Key has chip embedded and when one has to literally cut open the shell to access this chip.

The new key doesn't cost that much. It's around 1500 per key excluding the remote.

@Amit
If the transponder is not found, go for a new key and deregister the old key and remote from the ECU and security system to be safe.

Had a flip key in my i20 the internals held well till I sold the car. Problems faced were the keypad rubber wasn't very durable and was replaced once got it from ebay.

Also the plastic case started to come apart at times which used to activate the immobiliser leading to car not starting. Took it to the hyundai and they said the ECM was faulty and needed to be replaced as it only happens sometimes. So used a easier DIY using fevi kwik stuck the key fob together and used it for more than a year without any issues till the car was sold.

Our 2007 Honda Civic Remote (integrated type) works like a charm till date (touch wood) Be it mechanical / electronic functioning or the aesthetics, there is no deterioration.

Had a bad experience with Fiat's flip key though. The rubber buttons lost it's life in a couple of years.

I have transferred one of my original SX4 key into flip key. The transponder like many said here is the key. If dislocated slightly, can cause an issue. There is no other problem. It has been almost a year and never had any issues. Although I use both the keys every alternate month, even 5-6 months of usage has been trouble free. In initial days, I used to carry both the keys - just in case flip key fails, I can use the second original one. My 20 months old son has thrown a lot of abuse to the flip key and it somehow still holds good. Just to reiterate the step from the flip key making process - I had stuck the transponder chip closer to the key chip inside flip key and fixed using glue. I wrapped the transponder chip with paper tape and used a drop of fevicol to stick it!

In case if you find the transponder chip missing from the flip key - the only recommendation I would give is to replace both the keys and have the older ones decoupled from the car!

Look at the dashboard, the immobilizer icon must be flashing. I seriously doubt if the SA is/was trying to commit a future theft.

Just open the two screws of the key fob shell(one of the screws is exposed, the other is beneath the 'S' icon of Suzuki) and you would be able to see that the immobilizer chip has dislocated from its intended place which in turn is causing the problem.

The distance/proximity of the key sensor to that of the key hole is very very confined, a few centimeter distance can cause the Immobilizer to activate(have done this R&D before completing the key fob DIY).

Please open the key fob and you shall be surprised of the idiosyncrasy.

AND make sure to paste the immobilizer chip there with a good amount of glue so that you do not get this ugly surprise again at the most unexpected destinations.
I qualify you as the moderator of Team bhp.

You were spot on! Its actually the sensor/transponder dislocated and was sitting in other corner of the key. Many thanks for the detailed explanation.

Glad to post my query on this wonderful forum and got immediate solution.

Many thanks buddy!

This discussion gives a positive idea to those who have converted one of their remote keys (specially Maruti) to flip key that when they give their car to MASS for anything, always give original non-flip key to them to avoid possible theft of sensor/transponder from the flip key which can be taken easily by removing one or two screws.

Thinking a step ahead, one can even remove your sensor/transponder and put another similar looking non-working sensor/transponder in the flip key so that when you check, you will feel that sensor/transponder is still there and it has gone bad. And the culprit can steal the car anytime he wants (assuming he has already done other things like copying the key, etc.).

So, the bottom line is, never give your converted flip key to the service center.

I agree with you on not giving the flip key to the service guy. Infact, any after market modification can never be as reliable and sturdy as that done by manufacturer after proper R&D.

But, I have done a small-ish modification to my key FOB to make it tamper proof. I added a drop or two of fevicol to the screw hole which solidify overnight. Now, if anyone (chauffeur/parking attendant/service adviser) tries to tamper with my key fob, it can be known immediately. (This idea gave me feeling of a desi Sherlock )
Fevicol takes good 10-12 hrs to solidify and can be removed very easily in case I need to open key fob for any purpose.

Still, better safe than sorry. I avoid giving the key FOB to other people whom I am forced to trust for handing my car for brief period.

Regards

Thanks bubby for the brilliant Fevicol idea! I could not sleep entire night, thinking somebody at the dealership must have done the mischief of stealing the transponder. I really thank God that this episode took place in the dealership (near to my home) and not in the middle of road.

Having dropped the Hella units of two VAG Group cars multiple times, I can vouch for these guys to be one of the best in the business, if not THE best.

I have always picked them up after dropping them with my heart in my mouth, but always somehow finding them unharmed and in perfect working condition. Only very sharp drops or surfaces cause some small dents in the plastic.

OT, IIRC, some of the earlier Bugatti Veyrons also had this same key

Just wanted to share the durability of the Manza keys: Very bad. The rubber on the keys comes off very soon once they are exposed to water. Once they are off, water gets in and the whole circuit goes haywire, rendering the key useless in a few days.
