Keys
« on: August 15, 2020, 07:07:15 PM »
Now I know some of you have made your own, I don't have that sort of patients, I had thought about making one using resin, but at the end of the day the battery needs replacing occasionally and making two halves that screw together is just too mach of a headache.

So, my business imports a fair amount of tat from China. I also have various programmers for proximity transponders. China produces copies of near enough anything, including Ferrari Keys. I've tried to get them with the 4c transponder built-in, but they won't do them, not on the sort of numbers Ive requested anyway. So I have asked for samples no transponder (Ill add them myself) 433 txer with the TOY41 key blank. When I get the samples and get them working Ill be able to produce these for around £25-£35 with Toyota transponder and blank The price depends on numbers it cost the same to import one as it does 50, I shall import a few more than ordered for future requests. These keys are available on Ebay but not with the right transponder or TXer or keyblank.

Still early days yet I have no idea of the quality, and Im not going to China this year for obviose reasons, so I cant go and look before buying. But I toughts Id see how much interest there is.

Both Transponder and TXer are easily DIY programmed to your car there are loads of vids on utube showing how.

I've ordered two samples with TOY41 blanks 61USD depending on customs that should work out around £50.00 for the two. 4C transponders  cost £5 each, my programmer won't write to them so I need the key blanks in order to program them to my car. They are sending via DHL so it shouldnt take long to get here

I've spent time on this for my last 3 reps, and had success.

Have found:
1/ Although these Ferrari keys with internals are the same frequency 433Mhz, as the Toyota MR2 Roadster, they're not matched to the same sub-frequency, so you'll have a challenge getting the car to recognise and program them to it (let us know if you have success with that)
2/ Its posssible to make the Toyota key internals (incl the immobiliser chip) to fit inside these genuine key cases, as I have done, also picked up a spare on ebay, followed the usual guide to getting the car to recogise, and now have x2 nice keys. In the pic below, the MR2 internals are fitted in the Ferrari key case, and the Ferrari internals are taken out (seen to the left of that pic)
3/ You'll need to modify the rubber key side by increasing the plunger size a wee bit on one pin, so it hits the toyota microswitch "on the button". As in the pic, I've done this and seems to work fine. You only need to use two of the buttons on the Ferrari key case

Hope this helps. Brilliant if you can get these supplied with the correct MHZ though, it'd save messing about like I have.

Wow, thanks for that, from what I can make out the tx'r is 434 for real key, whereas Toyota is 433. I have asked for 433 I hope thats what I will get. I have ordered transponders separately and I although I do have a transponder copier I found there is a obd transponder programmer that works with MR2's https://www.youtube.com/watch?v=h3qBlIMtpXM&t=6s

This is the key I am being sent. it may take a while to come because I have arranged for them to be sent to a factory that I have a large consignment of proximity fobs being made. Until they are ready to send the consignment I won't get the keys. I've arranged for the transponders and the programmer to go to the same place, along with some other bits and bobs.

I think the length of the key blade can be an issue

That's the Ferrari blade, just replace it with yours or a blank TOY41 key and get it cut. The keys and programmer have been sent to my friend's factory in Shenzhen, I have also ordered a leather steering wheel cover to go to the same place. I hope that everything will be shipped by the end of next week. It will take around 3 days via DHL  so a couple of weeks and I will know if they're any good

Hi Redhot,

So I bought one of these key fobs a few years back, and gave up at the first hurdle, as I couldn’t see how to get the original metal blade out of the fob and the the MR2 blade into the fob without destroying the plastic ?

Any advice?

Hi Lee,

Yes I experienced that at first, had some success using a soldering iron on the metal blade to heat up close to the black plastic fob outer hoop, and wiggling a bit. I then realised these ferrari blank metal key blades have a small drill hole at the top (hidden inside the black plastic) and black plastic goes through that hole. A small drill bit sorted that out, soon as you're through one side of plastic, the drill soon finds the hole in the blade (if that makes sense).

This should leave a small rectangular hole in the black plastic part. Lay the MR2 key shaft end on top, mark the shape of the stub you need at the end (I used a metal scribe), for it to fit in the Ferrari fob, then start filing. Its soft metal, so pretty easy. I used Araldite 2 part epoxy glue to stick it in, and did my best to make the fit as snug as possible.

Hope that helps
