Because the CR2032 is 0.7mm thicker than the CR2025, it has a slightly higher capacity to deliver current to the load the CR2032 can deliver 225mAh with a thickness of 3.2mm, while the CR2025 only delivers 160mAh with a thickness of 2.5mm.

Can I use a CR2032 instead of a CR2025? Yes, you can use a CR2032 instead of a CR2025. Both batteries share the same voltage. However, the only concern is that the CR2032 is bigger than the CR2025.

Things To Know Before Calling Your Locksmith For Key Fob Programming

When programming a transponder key onboard or programming a remote headed key onboard, the locksmith will need to research several pieces of information before the process can be successfully completed. The locksmith will need to know the following:

  • What is the Year, Make, and Model of your car?
  • How many working keys you currently have?
  • Are you the current registered owner of the car?
  • Does the car require a BCM conversion or a Pin code read?
  • Did you purchase the key off Amazon?
  • Did you purchase the correct remote headed key?
  • Is the FCC number on the correct?
  • Is the battery of your car fully charged?
  • Should the locksmith program by vehicle or by type?

A lot of this lingo is locksmith specific, but it just goes to show that a lot of research is needed before connecting sensitive computer equipment to your car. The locksmith does not want to damage your car or their equipment.

Some remote keys can be programmed fairly easily on your own, and a professional locksmith will be able to guide you through this step with a simple phone call. However, many models require a complex programming sequence best handled by the locksmith, either at their shop or at your location via a mobile service unit.
