Inherited a 1 owner, low milage 1999 306TD Meridian Est with no keys an am trying to get it started rather than being sensible and scrapping it.

Bought a Lexia3(rev C allegedly) interface off fleabay with the usual software.

After literally a week, I have managed to get both PP2000 Ver(22.14 & 25.01) and DiagSys working. Tried a couple of old XP SP3 laptops, turned off wi-fi, av and firewall, uninstalled a few things re-interpreted the keygen and it works, but when I actually use PP2000 all I get is "The ECU has not replied". I then created a VM on my Windows10 Laptop, overcame the floating point CPU problems with Winfloat.exe but get the same "The ECU has not replied".

The program doesn't see the Lucas injector pump never mind show me the options for key programming, which is what I need to do to get it going. Autolocksmiths don't seem to be interested on the rare occasion that they pick up.

Does PP2000 work with diesels? Do I need an older version?

I am not sure about cars that old, but the usual fix for your situation is to get a matched set of BSI, engine ECU, and keys from a scrapped car of the same model, engine, etc.. This eliminates the need to program keys. You fit the new items, and swap the keyblades, so you don't have to change the locks. That presupposes the keyfobs have removable blades.

Bear in mind that Peugeot keyfobs cannot be reprogrammed to a different vehicle. Replacement keyfobs must be new and unprogrammed.

Try disconnecting the battery, put ign in position 2 and reconnect battery then try starting the car this sometimes reset the immobiliser

Forgot to mention - bought a set of used keys from fleabay and connected the ignition barrel, hence why I am trying to add the new code via pp2000.

I don't want to cut into the diesel injector pump to change the stop solenoid (and bypass the immobiliser in effect) if I can help it.

I think you are doomed to disappointment. The way Peugeot immobiliser works is to write a code to the key, which locks the key to the BSI and engine ECU. The key memory is "write-once", so you cannot use that key with a different BSI and ECU. That's why you need to buy the BSI, ECU and keys from the same vehicle.

Unless it's different for a car as old as yours.

I thought that this was a simple system on the phase 2:

1. Each key contains a small transponder containing a code.

2. A receiver ring around the ignition reads the keys code.

3. BSI checks if the key code is on the valid list.

4. Upon success of 3 the Ecu sends instruction to the diesel injector stop solenoid to release and allow fuel to be delivered.

I'm not familiar with Pugs though. Only other one I had was a 205 GTI 1.9 when I was younger - it kicked the backend out on a bend with lift off oversteer and went into a ditch, hedge then left me upside down in a farmers field!

As IanML has said twice, once a key has been matched with a BSI/ECU combination it cannot be used with any any other BSI / ECU combination. The only way round this is to buy a new virgin key or in some instances, replace the chip in the key with an unused one.

I would understand having to change a complete set if it was a rolling code system such as on later cars, but the phase 2 is not as far as I understand from the research I have carried out. It is a simple fixed code.

How would a new transponder chip help if it is blank?

The rolling or static code is for the rf side of the remote locking/unlocking system. The transponder chip is for the immobiliser - they are two different security systems.


A blank transponder chip CAN be programmed to the ECU/BSI pair enabling it to be used with the existing hardware. Once the transponder chip has been programmed once it cannot be reprogrammed to use on another car. A new key contains a blank chip up to the point it gets programmed to the car.


The chip gets the pairing information written to it during the programming sequence. This is a write once, read many type of chip so once it has been programmed it cannot be reprogrammed. Wishing or hoping it was different will not change the facts.

Thanks for articulating the facts.

Looks like there may be a problem to sort first elsewhere as I'm getting a hardly any potential difference/voltage from obd pin 7 (k line) and this would cause 'the Ecu has not replied' message.

All electrics seem to work bar the radio. All fuses tested good too.

UPDATE: Now working!

So returned the eBay lexia lead and bought one from Easydiagnostics as I had an on line conversation and he talked sense.

This worked first time, but the alpha PIN from Peugeot wouldn't enter. Later found that Pp2000 takes Uppercase letters only And Peugeot wrote down the wrong last character anyway! Once I got the correct Pin I tried key programing again and I got "Key programing failed" error. Did tests with the immobiliser and receiver but couldn't find anything obviously wrong - all the components seem to be in great condition befitting the low mileage.

Bought a key cut to code with and Id33 transponder but that turned out to be a disaster too - the key didn't work so asked Peugeot to check the code (after the Pin) but have been ignored.

After a few attempts I followed the Pp2000 diagnostics which indicates a wiring problem between immobiliser and receiver so I bought another immobiliser from eBay but with the same result on wiring testing. Tried key programing but no Pin! So swapped back to the original one.

So, decided to clutch at straws and try "resetting the bsi", removing fuse 8 and tried again but the same error. In one last attempt I thought that may be I could try to program the old (used) transponder. I pulled the fuse to reset and gave it a go and hey presto it worked. Checked the operation with pp2000 and saw a valid code was received and so tried and did start it! That old familiar rumbling was sooooo satisfying!

So it seems my original thinking was correct on how the process works. Pp2000 gives you some information on it. Just need to get the key situation sorted and the original stereo has no life, but other than that everything works!
