MAZDA KEY WANTED...

[Niko]

My missus decided to put my spare key to my 2010 MAZDA CX7 through the washing machine followed up with the dryer, a couple of weeks ago.

Result was the case broke open and the little diode type box inside has fallen out and gone to god while it was in one of the machines.

As a result, I can still get into the car with the key, but because it is not synked anymore due to the diode gone, it will not start the car.

If I can find a second hand one, with a diode still encased I can do a key swap and then with the help of YouTube.do a synking process which should pair the key to the car

Going through Mazda for a new key and then synk it up, is worth more than the CX7.

Thanks all.

You should be able to find a transponder with a housing pretty cheap online via eBay, without the key blade which you'd swap from your existing key.

If you can program it with the car, i'd definately do that.

if not, find a locksmith/hardware store with an automotive key copying machine (my local Mitre10 has one) and they can try copying the transponder of your old key to your new one (assuming you still have the old transponder) or failing that copy from your 'known good' key to the new one.

the ECU will just see Key 1 more often, rather than seeing Key 1 and Key 2 (as you've got two copies of Key 1). if your seat memory/radio station programming is attached to which key you have it'll mess that up though. It usually doesn't have any security rammifcations unless it's a post 2019 car that is expecting key sequences.

on most recent Fords (and other brands) the key programming is in the bottom of the cup holder, and if you have one working key you should be able to make another one.

Hi Niko I think rapid locksmiths offer that service at Bayswater

My local mobile locksmith did me a spare 'beach key' for my Amarok for $120.  This is cheap solution - you lose the remote function, but the key has a transponder and works like an "old fashioned key"   Waterproof and perfect for the beach and being treating poorly!

Could I have some more information on this please Fishcop.  I have a friend who has a pretty extensive car collection. One of his cars an AMG SL 63 has a missing key.  As such he cannot start it and move it out of his garage.  Luckily the car is unlocked so we can get inside but that is all.  The key type is like all current model Mercs.  I am unsure if a temp key can be made to fix my friends problem but if you can advise accordingly that would be appreciated.  Mercedes Benz solution is to jack up each wheel and place temp moving dollys under each wheel and then roll it onto a tow truck and ship it to a dealer so as MB can have a new key programmed for the car.

MB should be able to deliver a new key just using the VIN and proof of ownership?  Door keys like the one fishcop mentioned prob won’t start the car without the associated fob which usually has an RFID in it.  The key pattern is only there for the ignition lock, it’s the chip that communicates with the immobiliser and tells the DME it’s ok to start.

Ahh - I should have flagged up front that my car had an existing functional key - but the spare/second key got lost two owners ago.  I had heard horror stories of VW charging $850 for a replacement key (plus the whole flat-top thing).  We have a local mobile locksmith in Port Mac who specialises in vehicles (and getting people out of strife cheaper than factory).  He carries a CNC machine and blanks to cut perfect blade copies, and an RF reader which can read and duplicate the little glass ampule (RFID chip) inside the factory key and produces a duplicate to insert into the freshly cut blank.  You end up with a "classic" key which you have to insert and turn in locks to open doors and start ignitions - but also carries the RFID chip to talk to the car's immobiliser and engine management.  The great thing for me is it's waterproof and can come out for a surf with me when I lock the car.

Photos below of the original key and the duplicate - I took the little RF chip out so you could see what it is is.  $120 seems a lot for what it is, but the locksmith mentioned the gear involved is over $40k as he keeps correct licenced manufacturers' codes for most makes and models.  And a possible $1000 bill to recover the car if I ever got locked out made this seem cheap!

Ignition lock and RFID chip included   It definitely unlocks and starts the car - I just lose the ability to open the car remotely (and the cool windows up and down function on the original)

That's an easy one. Throw it in the bin and buy Webber's. 😉

Thanks I wasn’t aware some locksmiths had the tech to duplicate factory keys . Learn something every day.  It does make a mockery of the whole immobiliser thing though if you can just produce another key.

The mockery is what dealers charge!  The tech, licencing and equipment is highly regulated and protected.  It's no different in principal to using an independent mechanic rather than the dealer.  FWIW the guy that did my key also does the work for the local Merc and BMW dealer, but they supply the $800 key fob
