Are the buttons on your Nissan 370z Key Fob looking worn out and unresponsive? If your key fob is anything like mine was, the buttons probably look terrible after years of use. The good news is you don’t need to replace the entire key fob. You can easily and affordably restore it to its former glory by replacing just the outer shell and button assembly. I sourced a replacement key fob shell online for a fraction of the cost of a new key fob, and you can too.
This guide will walk you through the simple process of replacing your 370z key fob button assembly and shell. With a little patience and a small flat blade screwdriver, you can complete this repair in just 10-15 minutes. Let’s get started and bring your 370z key fob back to life!
Step-by-Step Guide to Replacing Your 370z Key Fob Shell
Step 1: Gather Your Parts
Before you begin, make sure you have all the necessary parts. You’ll need a replacement key fob shell designed for the Nissan 370z. These are readily available online from retailers like Amazon. Ensure your replacement shell includes the button assembly and any rubber gaskets needed. Having everything ready will make the process smooth and efficient.
Step 2: Open the Key Fob
Start by removing the mechanical key from your 370z key fob. Once the key is removed, you can access the seam to open the fob. Locate a corner on either the left or right side of the fob casing. This is where you’ll begin to gently pry it open.
Step 3: Separate the Case
Using your small flat blade screwdriver, carefully pry along the seam you located in the previous step. Work your way around the fob, gently separating the two halves of the case. Take your time and avoid applying excessive force to prevent damaging the plastic.
Step 4: Remove the Old Button Assembly
With the key fob case open, you’ll see the button assembly, rubber gasket, and the circuit board. Gently extract the button assembly and rubber gasket from the upper case shell. Lay out all the components, including your replacement parts, to ensure everything matches and you have all the necessary pieces.
To remove the old button assembly, you can use the flat blade screwdriver to carefully lift the rubber gasket and then the circuit board. The button assembly itself is typically held in place by small plastic snaps. You can use the screwdriver to gently pry these snaps apart or carefully flex the upper case to loosen the old button unit.
Step 5: Install the New Button Assembly
Take your new button assembly and position it into the upper case shell. Make sure to seat the alarm key portion of the assembly first, as shown in the image.
Ensure the new button assembly snaps securely into place using the plastic attachments. You should hear or feel a click as each snap engages.
Step 6: Replace the Rubber Button Gasket
Position the new rubber button gasket into the upper case shell. It should fit snugly and align with the button openings.
Step 7: Place the PC Board
Carefully place the remote PC board back into the rubber button gasket. It should tuck neatly into the gasket and appear integrated, as shown in the photo. Ensure it’s properly seated to ensure good contact with the buttons.
Step 8: Reassemble the Fob
Now it’s time to snap the key fob back together. Start at the “Z” end of the fob and gently work your way around the perimeter, pressing the two halves together until they snap closed. Be careful and ensure everything aligns correctly before applying pressure. If you encounter resistance, don’t force it. Go back and double-check that all components are correctly positioned.
Conclusion
Congratulations! You’ve successfully replaced your Nissan 370z key fob button assembly and shell. This simple DIY repair can save you money and significantly improve the look and feel of your key fob. In my experience, the original button assemblies tend to wear out after a few years of regular use. Fortunately, inexpensive replacement shells are readily available, making this a quick and effective solution to keep your 370z key fob in top condition. Enjoy your refreshed key fob!
