Pick up a new switchblade style key either from the online places listed in this thread (about $180 or so total), or off of ebay as mentioned above. You'll still have to go to the dealer to have the key / new fob programmed since you have only one.... What are my options??? I just have one switchblade key fob- no other keys.
In all the auctions that are on Ebay most sellers ask to compare the following numbers with the ones you have on your keys:
FCC ID: KPU41788
IC : 4238A-41525
Visteon No. 41525
What I have on my key is completely different.
MR 1382 ANRT 2005
CE C 5616
Mitsubishi Electric SKE126-01
Also none of the sellers offers a key that has the same buttons like mine. Instead of a panic button, I have a button to disable the car alarm.
Maybe I should add that I live in Germany and have a "European" Mazda 5.
Do the numbers of the keys you purchased on Ebay match what's inside the original keys?
I have exact same part numbers as your and the key looks the same without the third button, i only have 2 buttons and no third one as your disable alarm.
have you found any match?
I just ordered a spare key from Ebay
First of all: I was not able to program it for my car :-(
As I needed it as replacement for a broken key (which still worked), I just used the housing and put my electronics into it.
All keys together:
left the new uncut key, in the middle my original spare key and my broken key to the right.
I suppose it's due to the different circuits in the keys. As you can see one has the number JX331BA3802C, the other ends with 5802C
Basically they look identically, despite the battery contact and the IC:
One Chip is labelled MH860-DM98519K the other one MH860-DM98663K.
For completeness I took a picture of the numbers printed onto the key:
I'll go and ask the Ebay dealer if he has a key having a circuitry with the number my key has.
At least it was a cheap solution to get a "new" key. Cheaper then getting one from Mazda.
