NXP Killer Addon: Land Rover Solder-Free Adapter
NXPKiller Accessory · MCKB Series NXP Killer Solder-Free Adapter Clamp the board. Skip the soldering iron. A model-specific solder-free adapter for the NXP Killer NCF29XX cloning tool. Seat the key PCB, read, write, done - with no heat applied to an original smart key. No soldering NCF29XX smart keys Model-specific fit Repeatable bench workflow NCF29XX MCKB SOLDER-FREE RED - board not aligned with the adapter GREEN - contact confirmed, ready to read Seat the board Lift the board This is the whole job. A red light almost always means alignment, not a fault. Why solder-free Soldering an original key is the risky part of the job Reading an NCF29XX chip traditionally means putting an iron on a customer's original smart key PCB. That is slow, needs a steady hand, and one lifted pad turns a working key into a warranty conversation. A model-specific adapter replaces all of it with a clamp. No heat on the original key Spring-loaded pins make contact against the existing pads. Nothing is desoldered, nothing is reflowed, and the key goes back to the customer exactly as it arrived. Seconds, not minutes Clamp, read, write, unclamp. What used to be a careful soldering session becomes a bench operation you can repeat all day without fatigue. Model-specific, so it actually lines up Each adapter is cut for one board layout. The pins land where the pads are, which is what keeps the status light green instead of red. The workflow Four steps from original key to spare Open and identify Open the original smart key and confirm it carries an NCF29 series chip. Chip marking is the reliable check, not model year. Seat the PCB Place the board into the adapter so the pins meet the contact points. Connect the adapter to your NXPKiller unit. Read Press read. A steady green light confirms the read succeeded. Red means go back and re-seat the board. Write to the new key Seat the replacement PCB and press write. A steady green light confirms the write. The spare is ready. Reading the indicator What the light is telling you The status light is the entire user interface, so it is worth knowing exactly what each state means before you are standing over a customer's key. Steady green The operation completed. After pressing read, a steady green light indicates a successful read. After pressing write, a steady green light indicates a successful write. Red during read or write The circuit board is not aligned with the adapter. Lift the PCB, reposition it so every pin meets its pad, and try again. This is the most common issue and it is a seating problem, not a hardware fault. Lights up, then stops responding The power connection is unstable. Disconnect and reconnect the power, then repeat the operation. Compatibility Built for NCF29 series smart keys The NXP Killer copies most smart keys carrying NCF29 chips. Adapters are sold per board layout, so confirm the adapter matches the key you are working on before ordering. Chip family NCF29A1NCF29A2NCF29A3 NCF29A4NCF2953NCF2954 NCF29AG NCF29AG is not supported. If the chip is marked NCF29AG, this tool cannot copy it. Vehicle brands commonly covered HyundaiKiaToyotaNissan BMWJeepDodgeRAM ChryslerMazdaMitsubishiHonda FordChevroletGMCCadillac Land RoverAlfa RomeoFiatPeugeot RenaultSuzuki Coverage depends on the specific chip variant and board layout, not on the brand alone. Different vehicles need different adapters - one adapter is not universal. Before you clone Four things worth knowing first These come straight from the manufacturer's guidance. Reading them now saves a callback later. PCB choiceUse an OEM PCB, not a universal one When choosing a PCB for the cloned key, prioritise an original manufacturer PCB of the same model. An identical OEM board gives the best result for chip type, circuit design, RF performance and antenna matching, producing a key that behaves like the original. Universal aftermarket PCBs should not be used. Rolling codeSell it as a spare, not a second daily key Once cloned onto a compatible PCB, the copy is functionally interchangeable with the original. However, alternating between an original remote and a cloned remote on the same vehicle can cause rolling code desynchronisation, which can leave the remote function of one key inoperable. Recommend the clone as a spare key. Land RoverUWB models need extra care Cloning is possible on Land Rover. On lower-specification models the process is straightforward. On high-specification UWB models, cloning causes the Ultra-Wideband function to fail, and the vehicle's UWB function must be disabled beforehand - otherwise the vehicle will not recognise the cloned fob, because the onboard system needs a valid UWB signal to unlock and start. MythThe "256 presses" story is not true There is a persistent claim online that a cloned remote stops working after 256 presses. It does not. The key continues to function normally. What can still occur, as with any clone, is rolling code desynchronisation. Questions NXP Killer adapter FAQ +How do I confirm a successful read? After pressing the read button, the green light will stay on. A steady green light indicates the read succeeded. +How do I confirm a successful write? After pressing the write button, the green light will stay on. A steady green light indicates the write succeeded. +Why does the red light appear when reading or writing? The circuit board is not aligned with the adapter. Lift the PCB and re-seat it so each pin meets its contact pad, then repeat the operation. +The tool lights up on power connection but stops responding. What now? The power connection is unstable. Disconnect the power, reconnect it, and try the operation again. +Can I read once and copy to many keys? Yes, if you are using an unlimited version device. Limited versions allow a fixed number of uses. +Is there a usage limit on the device? There are two versions of the cloning device: an unlimited version with no usage cap, and a limited version with a fixed number of uses. Check which version you own before planning a job. +Which keys can it copy? It can copy most smart keys fitted with NCF29 chips. Open the key and read the chip marking to confirm before quoting the customer. +Can it copy NCF29AG chips? No. NCF29AG is not supported. +Does the cloned key still need OBD-II programming? Once the original key has been cloned successfully, the cloned key typically does not require further programming or pairing to the vehicle through the OBD-II port. +Which PCB should I use for the cloned key? Use an original manufacturer PCB of the same model as the key being cloned. This gives the best compatibility for chip type, circuit design, RF performance and antenna matching. Universal aftermarket PCBs should not be used. +Can the original and the cloned key be used interchangeably? In theory yes, once cloned onto a compatible PCB. In practice there is a risk of rolling code desynchronisation when both are used on the same vehicle, so the clone is best used as a spare key. +Does one adapter fit every vehicle? No. Adapters are model-specific and cut for a particular board layout. Match the adapter to the key PCB you are working on. Using the wrong adapter is the usual cause of a red light. Clamp it, read it, move on to the next job A solder-free adapter is a small purchase that removes the slowest and riskiest step in NCF29XX cloning. Match it to the board, watch for the green light, and keep the iron in the drawer.
