Key fob broken 20 November 2022 at 12:19PM in Motoring 7 replies 189 views

Hi
I have two remote key fobs for my Hyundai i30. On one, the metal ignition key has snapped off and 
the buttons have worn off on the other.
This means I have to carry two around if I want to use remote lock/unlock.

Not sure how much it would cost for a new one but was wondering if it’s possible to swap the ignition key over
to the working remote.
Have tried to get it apart but finding it difficult. 
Any help appreciated.

If you look at how to replace the battery you may find its a two piece clamshell with the circuit and battery on a removeable circuit board.

You may be able to swap the pieces to make a fob which works.

Youtube is usually a good resource for how to do jobs like this.

Try a key-cutting place - Timpsons, maybe.

Agree, try somewhere such as Timpsons. Failing that are you on a Hyundai car forum? If not, join one; try i30ownersclub.com.  Generally a good source of brand related info. I’m on such a site and there’s a guy there who actually repairs key fobs.
Try and avoid sourcing a replacement from a main dealer, it’ll likely cost an arm and a leg
Further update - just had a look on that owners forum and there was indeed a thread for this exact subject started under the heading ‘broken key’ on 2 November 2009. Seems they resorted to dealer under warranty.

Does the one with the worn buttons not work at all ?

You can get a new case and uncut key on Ebay. https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=hyundai+i30+key+fob+replacement+case&_sacat=0&LH_TitleDesc=0&_odkw=hyundai+i30+key+case&_osacat=0

Just be aware if you get the new case there is a transponder chip for the immobiliser embedded in the case that needs to be carefully removed and can be a bit of a pain to safely get out.

If you look on eBay, you can buy just the rubber buttons for £3, or better, a complete case with a new key blade for £9.

Then you can get the blade cut to match your working key at your local keybar- Timpsons probably won't cut a blank they didn't sell.

You have to swap all the innards over, being careful not to lose the immobiliser chip (if there is one, Hyundai/Kia couldn't be bothered fitting immobilisers to some vehicles, which are now spectacularly easy to steal, almost as easy as a keyless Rangerover)

So you can end up with two working keys for a few pounds.

There are hundreds of videos on youtube showing how to take them apart, look for hyundai key fob, hyundai flip key case.

The unlock button works ok and still has the cover. Thought using a pen to push inside the other two would operate them but doesn’t. 
Maybe a couple of new buttons as suggested would work.
