I had 3 broken key fobs, electronics were good, but casings were broken at the ring. I could have ordered new covers, but at a cost of around $20 dollars each and $40 shipping to Canada..it was way over $100 with tax. My 10 year old GM is not worth that for keyrings.
This cost $1.25 + tax for wire and I have enough to fix 100 key fobs.
Step 1: Tools
Assemble your tools. Drill with small bit, Pliers, 22 Gauge wire and coin.
Step 2: Open the Fob
Pry it open with the coin
Step 3: Drill Holes
Drill holes in the plastic
Step 4: Prepare Wire
Cut short length (about 1-1/2") of wire and bend
Step 5: Insert Wire
Insert Wire in holes and pull through
Step 6: Bend wire
Bend the wire to line up with the groove in the case
Step 7: Close Fob case
Align shells and press closed. Put the keyring through the wire and enjoy.
Step 8: Finished
I did the first one in about 10 minutes, the next two took me about 2 minutes each, no problems yet.
