• The 'Unit supplied with PIN number' option above is for the the supply of a replacement unit with its immobilizer 'PIN' code (Security pass details) so it can be 'RESET' & programmed to your vehicle with the necessary equipment (Opcom or similar) - If you do not have programming equipment we also offer this unit with a 'Cloning service' included at extra cost - Please see the other purchase options & services below
• The 'Unit supplied & cloning service' (Exchange unit) option is for the both the supply of a secondhand unit & the programming service (Cloning - Data transfer from your unit to this donor unit) To do this you will have to send us your old unit. Once we have received your old unit we will transfer the immobilizer data from your old ECU to this supplied unit & return you a replacement unit fully programmed to your vehicle. This unit will then plug straight in and work on your vehicle with your existing keys etc  with no further programming necessary. Your vehicle mileage etc will be unaffected by this process & will still display your vehicles correct reading. You will not have to program keys / central locking keyfobs etc after installation.*we can extract the necessary data whether your original ECU is completely dead with 'No communication' with a diagnostic scanner*.
• The 'Cloning service only' option is for a Cloning (Data transfer) service BY POST ONLY – We are NOT supplying the unit!! If you have a faulty ECU (Electronic Control Unit) / Module on your vehicle, for example it may be water damaged or have a blown component and are looking to replace the unit you may be aware that you cannot simply remove an unit from another vehicle & install it onto yours as the unit is 'Locked' to a different vehicles electronic / immobilizer system. We have the solution! Simply send us your original (Faulty) unit & the donor (Replacement) unit & will will transfer the data from your original to the replacement enabling the used unit to work on your vehicle with no further programming necessary. Once the donor unit has been programmed (Cloned) your vehicle will then start & run, the mileage display & the central locking etc will be unaffected & operate as it should. *we can extract the necessary data whether your original ECU is completely dead with 'No communication' with a diagnostic scanner*. We are not supplying an ECU with this option
• The 'PIN code retrieval service' (Security pass details) option above is to be used when a secondhand ECU needs to be 'Reset' & programmed to a vehicle via diagnostic tools & the immobilizer security PIN code of the unit is unavailable / lost. For example if a secondhand unit has been sourced from a breakers yard without its PIN number & the original ECU is missing / unreadable so it cannot be cloned this will then enable programming functions to be performed. We are not supplying an ECU with this option
