Do you think your remote keyless entry signal is weak? Probably the rate at which it responds is not as effective as it used to be. Is your car remote not functioning properly? If this is so, then it is a sign that you need to get the batteries changed. We at Quick Keys will appreciate it if you let us run a check on your remote battery, and probably make a change if possible. This is a cheaper, and the most convenient way to get your remote working again.
