My Pontiac Remote is more than twelve years old. I replace the battery twice if my memory is not wrong.
Last month, the remote is not working any more. No matter how hard I press the rubber button.
I also clean the contact parts with rubber. Still not working.
After a few search on eBay and Amazon. The replacement of remote is more than $20. And also it is hard for me to program the key fob.
Later I bought a set of fob from Taobao. Actually it is not a completed set, but just the case and rubber. CNY15 each. I paid CNY 30 for two cases. Convert to Canadian dollor is CA$6.
Lool at the place red arrow pointed. The contact part, which is conductive, is almost gone.
I just open the original one and replace the rubber, all match. The Pontiac SV6 key fob is working now.
