Lock barrel makes non odds so it must be the key,

Did he damage the chip when removing it from the old key?

 

Does he have another old chipped key?

If yes - try taping that to the column and going for a test drive. If the cars fine, you've found your problem.

this is what i been told happened steering lock went so the lock got replaced with matching key the chip off the old key got put in the new key that came with the barrel then they were told it should work in theory but it wont they then tried to reset by leaving battery off and now the light on clock does nothing and key does nothing but they have been told key needs recoding ?

I assume that you're talking about PATS? Valid key codes are stored in non-volatile memory inside the ECU or PATS module and cannot be reset by leaving the battery off.

 

You cannot recode a normal Ford key as they are manufactured with a unique code pre-programmed into them which cannot be changed. When people say 'coding a key' they really mean coding the ECU to accept the key. Locksmiths can clone a key though by copying the original key code to a programmable blank chip.

 

They may have:

 

not plugged the transceiver in correctly - check plug is in properly with no bent pins

damaged the transceiver ring when the column lock was changed - look at plastic housing for signs of damage

damaged the key chip when removing it from the old key - remove red plug from key, shake key chip out, slide off rubber sleeve and check that glass vial is intact

all thats been changed is the barrel, the chip put from old key into new key and when key is placed in the ignition and turn pats light flashes

 

chips fine transponder is fine nothing else has been changed or unplugged

Without a spare original theres not much you can do.

I'd say the chips been damaged somehow if you're sure everything else is fine.

 

What age is the car? You can bypass the PATS in an older model, mk5 for example, as its external to the ECU.

They got one key with the barrel and have the red key and two or 3 other keys for the original barrel. And its a mk6 on a p reg

Well if they've got some other 'original' keys, do what I said about taping one to the column or sensor ring.

 

As long as the ECU can 'see' the correct key it'll let the car start.

 

If it works I'd be tempted to stick the key there permanently, glue it behind the plastic cowling or whatever. Nobodys gunna pinch a 1400 escort these days.

I tried sticking the key there it makes no difference when i put key in and turn i get pats light on clock keep flashing

You sure the transponder ring isnt broken or unplugged?

You could try a new ring?

Must be another member on here who can give/sell you one from a breaker.

Fairly certain the rings are all the same, its just the ECU and key that have to match each other.

Looking at it yesterday it looked fine but saying tht i thought u have to. CHange more than just the barrel for it to work like i said its only the barrel that got changed i held the chip to the colum to try that i tried 2chips i tried holding the master key near it but all i seem to get was. When u turn the key to ignition the clock light flashes quickly and wont do anything if i try to start it which say its not reading the chip
