Glad I Had A Spare Key Cut

[marsh man]

In all the years I had been driving cars and lorries I had never had the problem I had yesterday 

We had taken the dog for a run down the marsh and all was fine , getting back in my motor I put the key in the ignition , turned it and then the key and holder fell to bits , the key itself was in the ignition and the other bit were scattered on the floor , I could turn the key but it wouldn't start and the green key symbol came on the dash , as luck would have it my wife had the spare key with her , so removing the old key I was back on the road again , I have now ordered a blank and I am hoping I can change the inside bits of the old one into the new one .

You clever lot would know , would this work , or have I got to have another key cut ?

The car is a Honda CR-V .....     THANKS

Does the bits that fell off contain the immobiliser fob or bits?

If so you need that as well. Sometimes it's just a little magnet type thing that needs to be near the ignition barrel.

Sure someone will have the technical terms for it all😁

I did that on a Vauxhall. There's a little transponder chip in the plastic which needs to be within a certain distance of the key barrel. Your car would have started if you'd held the bits of the handle or the other key near the barrel while turning the broken key.

I did manage to put the bits back together when I got home and it did lock and unlock the car on the buttons, but I daren't try it in the ignition as the key fob itself didn't look that strong .

THANKS

Yup,  that's what I meant a transponder, couldn't think of the name, old adled brain

Yep, the TXPDR or transponder is basically an RFID chip and needs to need within a certain distance of the ignition barrel antennae loop ( other later keyless works on similar principle but distances are greater- hence the current spate of ‘relay’ thefts )

From experience its either embedded on the pcb or separate within the fob and looks like a piece of graphite about 5mm to 10mm long.

Don't quote me, but I think Timpsons can cut and programme keys? Which would be Lowestoft branch for you I believe that does car keys

Find the transponder chip and verify you can start the car, temporarily tape it near to the ignition barrel if you have to, and use pliers to turn the key if necessary. Once you’ve done this, go on eBay and search for the make model of your car + key fob. There are independent specialists who will build your transponder into a new remote, for a fraction of the cost of the dealers, and likely better value than Timpsons. You do need to send the existing bits to them registered post, and you may have to program the fob to the car (google is your friend). I did this for my Discovery 2 for £30, which was a bargoon compared to what LR would’ve charged!

Always worth keeping a bit of bluetack in the glove box! Use it to stick the transponder to the cowling under the ignition barrel if your key snaps!

I have changed key fobs twice on my Hyundai - the original broke and the first cheapo eBay replacement kept falling apart.  The second eBay fob is held together with a screw and, so far, is fine.

I used my original key blade both times and switched the transponder and the remote locking circuit board over with no problem. The only difficulty that I did have was that the original location slot for the key blade did not correspond with the hole in the eBay fobs, so I had to file a new slot.

From memory the fobs were less than a fiver each on  eBay and took a couple of hours for me to convert.

Yep, had the key go on my car and looked up on the web, found a real nice chap who was runing his own little business going round sorting keys for people. He sorted mine and also provided another spare , I think I paid him £35 all in.  He was disabled as well but not sitting on his backside drawing at the Post Office every week but he said he was making a nice living at it.
