Hi all, I am chasing 2 x Mazda 323 Keyless Remotes Part # 41601, they appear to be like hens teeth !, Is there anyone can assist ?, I have looked on eBay and they [41601] are not to common, I would like to purchase 2 at the same time. the reason I need to 2, is that I recently purchased a 2002 Mazda 323 Hatchback vehicle and it came with 2 remotes. But, they both seem to be intermettently faulty, thinking the simple fix would be the batteries, well its not that , because they still do the same, can somone advise accordingly, thank you in advance.
