WiseSeek replacement key fob kit plugs into your vehicle’s OBD port to program two M3N32337100-style remotes for select GM trucks and SUVs in minutes.

If you need an extra keyless-entry remote or lost an original, this WiseSeek DIY OBD2 programming kit lets owners add two replacement M3N32337100-compatible fobs without a dealer visit. The kit is designed for many Chevrolet and GMC models from roughly 2014–2021 and follows manufacturer communication protocols so it integrates without re-flashing the vehicle’s ECU in most cases.

Which vehicles will this WiseSeek OBD key kit work with?

This kit is built for select GM trucks and SUVs. Check your vehicle year and key part number before purchasing to confirm compatibility and avoid issues if your vehicle has nonstandard security modifications.

• Compatible families: Chevrolet Silverado 1500 (approx 2014–2019) and Colorado (2015–2021).
• Also fits GMC Sierra (including Denali trims, approx 2014–2019) and GMC Canyon (2015–2021).
• Requires vehicles that originally use the M3N32337100-style remote.
• If the ECU or security system was replaced or altered, dealership reprogramming may be necessary.

How do I program the replacement remotes using the OBD port?

Programming is performed by plugging the WiseSeek module into the vehicle’s OBD-II port and following on-screen or supplied instructions. Typical setups take only a few minutes per remote and don’t require specialized tools beyond what’s included.

• Insert the unit into the OBD-II connector (usually under the dash) and turn ignition as directed.
• Follow the programming steps to enter learning mode and press buttons on the new fob when prompted.
• Complete the sequence to store the remote in vehicle memory; test locking/unlocking and remote start if supported.
• Retain original remotes for reference; some vehicles limit the number of stored remotes.

Is this kit safe for my vehicle’s electronics and security system?

WiseSeek built the kit to use OE communication methods so it interacts with the vehicle’s existing systems without altering ECU firmware. That said, vehicles with aftermarket security gear or replaced ECUs may not accept the remotes and could show persistent alerts.

• Operates on manufacturer-standard protocols to avoid ECU reprogramming or warning lights in standard setups.
• Does not attempt to bypass factory immobilizer; it adds remotes through the car’s learning mode.
• If your vehicle has a replaced or upgraded security module, a dealer may be needed to complete pairing.
• Contact WiseSeek support before attempting programming if you suspect prior ECU work.
