Peugeot car keys used to be good quality. Until 2006, when flip keys came out,  keys had the old fashioned type of transponder chip, making these older style keys were very reliable.

We’ve never seen a Peugeot Car key problem with the old style of chip in fourteen years. They never go wrong. The worst thing that happens is when you have a key that looks like this. A key with holes instead of buttons will still start the car. The microchip matters, not the buttons.

My Car won’t start after changing the case

If you have a key that looks like this, did you buy a key case from eBay and try to swap all the parts over ? If you forget to transfer the small chip, (thinking that the green circuit board is the important thing), you have a problem. The circuit board isn’t important, not as far as the car starting.

Throwing away the chip with the old case means the car won’t start. But unless this has happened, there’s no reason to think that there’s anything wrong with your car key. Take it to your local car key man and ask them to read it in the car key machine for free.  They’ll tell you if the chip is still reading ok. If it is, there’s nothing wrong with the key, there’s something else stopping the car from starting.

My car has forgotten the key

No it hasn’t. Peugeot Cars never forget the keys. Reprogramming the keys is a waste of time and money. Take it to a garage and get an expert on the job.

New style Peugeot car keys

If you’ve one of the newer style keys, you’re in one of three stages of Peugeot car key ownership.

  1. You’ve just had a brand new car key, everything is great thank you.
  2. You’re frustrated that the keys are worn out, because the car doesn’t start sometimes.
  3. You’re stranded somewhere because you have a serious Peugeot car key problem.

The good thing is, you’re in a big club, it’s not just happening to you. In fact, just like a Blue Peter badge, you should have an ‘Anti-theft’ badge so that other Peugeot owners know you’ve also been stuck in some Tesco car park for hours on end, trying to get the car to start.

The problem is world wide and our video has been watched from Albania to Zambia.

If you have a Peugeot, at some point, you’ll have a Peugeot car key problem.

Info Anti-Theft

If you’re getting this message, read on.

The flip key does not have a separate transponder ( unless it’s an early 1007, but this is an exception). The chip is what we call a ‘virtual chip’. Delicate components work together, to generate a chip signal. Unfortunately, if a butterfly flaps it’s wings on the other side of the world, it’s enough to make the Peugeot car key problem happen wherever you are. A dropped, squeezed, thrown, opened and mis-treated car key, eventually won’t start the car.

It starts as an intermittent problem. Initially, the car won’t start every now and then. It gets worse, until you are crossing fingers everytime you try and start it. Ignore this problem and you’ll be stuck somewhere, at night, in the dark, in the rain. The breakdown man will ask ‘How long’s it been playing up?’

Citroen car key problem

If you’re getting this ‘anti-theft’ message, the key is probably faulty. It won’t help to have the key reprogrammed. Compare it to tyres worn on just one edge. They’re worn out. It won’t help to have the tracking or balancing done. They’re worn out,  just like your car key.

Don’t waste your time and money getting the key reprogrammed.

Getting a new Peugeot Car key

There are three things you need.

  1. A brand new key. (don’t waste money on a second hand eBay key)
  2. The security or ‘Transponder’ Code
  3. Someone to cut and programme it.

A good Auto Locksmith will have special equipment, that will extract the security code from the car. This means they won’t need the code. The dealer cannot do this.

We hope this helps. When you have a problem, sort it out early so the breakdown man’s not asking ‘Has it been like this for a while?’

      Hello, I expect your car key is faulty. You need three things. Firstly a new key, next a transponder code ( a pin code for the car) and lastly the correct computer software to code it in to the immobiliser.
      I expect your local repair garage will have the number of someone who can do this for you
