Remote key, FSK or ASK?

[bebu190]

Yes indeed wheeler and ozvtr ... thanks for trying to resolve this, i have no separate electronic within the key shell / housing / case.... everything is soldered on the remote car key.... :/

I didn't try to open the non remote car key that works. And not sure they can clone from a different type of key and also if with all information about the car (car registration documents) a locksmith can re-programmed the transponder.

I have attached a picture of my board and googled ID46 transponder on the web, the kind of tranponder that shows up seems a bit different.

So if I order a virgin clean board to program i would have the same issue regarding programming it.... yeah i will try to go next week to a locksmith and see what they think ... but in my mind a locksmith does key for your appartment, any locking doors or whatever... i was miles away to think that a simple locksmith would have the appropriate tools for car key issue

That's not the coil that I was talking about. That's the antenna (coil) for a PCB transponder. I don't want to make this thread more complicated but you can get keys that have the transponder as part of the circuit board or the transponder is separate.
To my knowledge the genuine keys have a circuit board for the transmitter and a separate ID46 transponder 'chip'. I have only seen the Chinese knock-off keys use the "on PCB" type transponders with the discrete coil. So I don't think your key is original, but....I could be wrong.
Seeing as the second key works (which would have made this thread much shorter if you had mentioned that in the first place ) you can get a new transponder "cloned" and replace the transponder that doesn't work.
A locksmith or auto locksmith can clone a transponder but they need an original transponder (or whole key) that works with your car.
Or you could just take the transponder out of the working key and put it in the non working key. Of course, that wont work if the transponder is soldered onto the circuit board.
I am not sure but I think there is something strange going on here.
I would recommend taking both keys to a locksmith and see if they can sort it out for you.

And no ozvtr i don't think it is a chinese car key copy... my car key seems pretty genuine.... the picture i took is the one that is the closest match to my current board the difference being that I have the chip represented here near the two buttons on top of the board and another smaller chip instead (so two chip on the board) and the quartz is not at the vertical but horizontal.... lol

The majority of PSA cars now have 'on PCB' type transponders & not seperate transponders on the remote keys. This is how they can be flashed & re used on another car with the right tools.
Yes the ID46 transponders can be cloned but this is no good if you want a remote key as like you say its the transponder that gets cloned.

Fair enough, technology moves on.

"different type"? What do you mean by different?

No, the Locksmith reads the (good) key electronically and then makes a copy of that key's transponder. You don't need any documentation, you just need the key that works. Hence the term "cloning" (copy). They should be able to tell you if the transponder is working and if it can be re-programed. Either way, they should be able to give you some sort of solution.

There is a big difference between a "locksmith" and the guy who cuts keys in the shopping center. You are probably thinking of the people who fix soles of shoes and cut keys, that's not what I'm talking about. Typically a locksmith will have a stand alone store and they only deal with locks and keys, including electronic locks.

Ok cheers ozvtr i'll try to find someone in town that can fix the key then.

Yes I said different type as i have two types of keys see attached (one remote and on non remote) so i don't know if "copying" ones on the chip would work as wheeler also mentioned.

RE KEYS AND REMOTE LOCKING,
just a general observation, the chip required to start the car used to be in the key and the locking function in the remote. Now many makers have just one chip to do both hence incorporating just push button start no physical key.

One thing with most if not all current locking systems is that they use a rolling code in that each time the remote is operated it uses a new code based on an algorithm and only the cars system knows what that code will be. ( This prevents thieves using a receiver in a car park to copy a code )

Additionally most remotes were based on a 64bit system which means if your don't use the second remote, after 256 shots with the first one the second one won't work and of course the battery is blamed. But the remote has to be resynched on some cars this is a dealer task on others there is an owner procedure available.

As an example the old teardrop and later remote supplied with C5's cannot be reprogrammed for another vehicle or code.

6490S2 for an un cut remote key £139
6490S3 for a pre cut remote key £198
These both still need to be programmed too.
Dealer keys are massive over priced & in my opinion the rectangular flip keys are not that great quality either.

I had one cut and programmed for my Civic, done by a mobile auto-locksmith.
It is actually a Peugeot fob
£130. Honda wanted £300.

Hello, my car is citroen c5 X7 2011. I will buy a new key because the original key of my car is broken. The problem is that citroen used two types of keys in 2011, FSK and ASK. Since my car is a 2011 model, I don't know what type of key it has. I would be glad if you help. Additional information: I am the first owner of the car. I bought it on February 23 and received it on March 3, 2011. (I wrote it from google translate because I'm Turkish, the language is a little bit bad, sorry.)

[wheeler]

Will likely be ASK
