Backup Key . . Transponder issue . .

[TC542]

Hi All . . .
Recently purchased Peugeot 208 Allure, but only received 1 Key from the dealer.
I went to Peugeot dealer to get a replacement mechanical key and get it programmed.
(I believe that the 2nd/backup key has a transponder in it . . . )
However, The key arrived from France already cut, but the service people are telling me that it doesn't come with a transponder . . .??!!
Why have a backup key if it doesn't have a transponder . . ??? . . If you lose your remote keyfob, then you need a backup that you can start the car with.
Can anyone please confirm my belief or am I completely wrong . . ?

I have recently bought a smart Remote Keyfob . .with a '4A' type transponder . . that I believe is the correct one for our 2023 Allure.
Does anyone near to Milton Keynes have the tools to program it along with my original . . ?
Many thanks in advance . . . TC542

Just so you can wait a week or so while the real key arrive, I suppose.

How much did you pay for this key. I understand that you purchased a backup, and that’s different to what I purchased about 4 years ago after my 307’s key got very dirty and it needed a full cycle in the washing machine. I paid $300AUD for a new full replacement key, including coding and delivery from France to Australia

Cheers,
Andrew

Can you confirm if the car is push button start? if so then the mechanical key has no transponder in it at all, its purely for unlocking the door if you have electrical power failure or the fob fails.
The backup transponder is actually inside the fob itself, if you hold the fob against the pickup on the steering column this will allow you to start the car even if the fob battery is dead, this is the backup.

If you have a normal keyed ignition then the basic key should have a transponder in it. To program it you would need the 4 digit security code unique to your vehicle

Hi . . .
It is a push button 'Start/Stop' system.

Before I go to Peugeot tomorrow to complain . . .
I have a receipt for the supply and the key code for the manual(Not keyfob!) key.
Why request the key code if it doesn't have a transponder.
I contacted the Northants Peugeot dealer and the the service guy said that the backup key should have a transponder . . or else it's useless.
He said to go back to the Milton Keynes dealer and get it sorted.
Today I tried the key supplied . . . without the keyfob(transponder) nearby . .Opened the door . .and the alarm went off. . . .!!!!
Not surprising, as there was no transponder . . !!

I'll update all tomorrow after my visit to the dealer . . .

Why request the key code if it doesn't have a transponder.

The key code would have been the mechanical cutting code so the blade comes pre cut to fit your lock.

He is wrong im afraid, the mechanical backup key 100% does not have & not meant to have a transponder.

On a push button start model the ‘backup’ transponder is inside the actual remote.
Try it yourself, take the battery out of the fob & sit inside the car, it wont start when you press the button, hold the remote against the backup receiver on the steering column & the car will start.

Hi All . . .
Just an update . . I went to the dealer, explained about the 'manual' key setting off the alarm . . Just said,in effect, "Oh well'. . .
I bought a remote keyfob from eBay, with the, I believe from various sources, a' 4A' transponder. . . .(Peugeot 208 Allure 2023)
I took it along to the dealer, he took it into the service dept . .
He came back saying that the keyfob will not work as it has not been supplied by Peugeot (France) . . ??!!
I have seen many posts saying that they have obtained a keyfob and then programmed it using the Diagbox. Lexia, etc.
On a video, I saw the system uploading the Keycode, followed by programming 2 or 3 keyfobs.
My eBay keyfob has the 4bit keycode on the packaging . . WITHOUT the key being cut. . . !!
So, is the 4-bit code, letter code, for the mechanical key cut pattern or the transponder . . ?

If anyone can help in the programming of the eBay keyfob, along with my current working keyfob, it would be greatly appreciated.
Am located near to Milton Keynes.

Thats not true either, the keys on this car dont use 'pre coding' so are not unique to any specific VIN, doesn't need to be ordered from the dealer. However it is an ebay key so there is absolutely no guarantee that is the correct one for the car or that it will even work.
Did they even try to program it? I do understand that dealers can be reluctant to program in parts from unknown sources, What if it bricks the car? who is taking the blame?
Would you take your own burger into McDonalds & ask them to cook it for you?

The mechanical cutting code on this car is HCA followed b 4 number (eg HCA1234)
The key programming code is a 4 digit code that can be a mix of both numbers and letters (excluding I & O)
I highly doubt that this will be the code on the bag of an ebay key, Did you provide the seller your VIN? they would have neede this to obtain the code & it is unique to your car.

Cheers Wheeler for the update to my queries.
The dealer is going to try and program the fob(s) in Sept. . . at a charge of £75.
They are not going to give a discount for providing a key that is absolutely useless . . That cost approx. £52 . .!! . . ("Lock Key + Key code retrieval")

I was just hoping that someone fairly near could do it for me . .

[wheeler]

They are not going to give a discount for providing a key that is absolutely useless . .

I disagree with that, its not useless, its actually essential.
Assuming you never had one already.
If you ever have a dead 12v battery by leaving your lights on by accident for example how were you planning on getting in the car top pop the bonnet & jump start it??

As i said before you do have a backup transponder already, its inside your remote.

Ok . . . But, I would have the key on my fob to open the door . .
(But, I'll keep it for that one off instance . .

Just opened up the eBay remote and compared it with my working original . . . No 'IM3A/ID4' transponder . . ??!!
(Am trying to find out from the supplier what's happened . . )
Meanwhile, I have cancelled the dealer appointment until I found out about the new item.
Will update when I have more info . .

So you already have a mechanical key blade for the car??

How do you know there is no 4A transponder in it? You really need a reader like this to tell.
The internals of aftermarket keys i find rarely look identical to the OEM boards.

Hi Wheeler . . .
Yes, I have the original side/manual mechanical key on my remote.

I contacted the eBay seller . . He stated there is an integral transponder . .
So I opened it up again and found the 'IM3A/ID4D' transponder on the underside of the circuit board . .
He said to try programming . .It should be okay.
So just need to find someone to help me program it . . .

Hi . . .Again . . .
I am thinking of getting one of these for sorting various issues on our Citroen and Peugeot . .
"LAUNCH X431 ELITE 2.0 For Peugeot/Citroën Car Scanner Diagnostic Tool" . . from eBay.
Does anyone have any experience of this unit . . ?
I have asked the supplier if it would be able to program my spare 'smart' remote keyfob.
(I know it could program a manual/key ignition type . . .)
Any help would be gratefully received.
