The Infiniti 2006-2010 M35 and M45 models came equipped with smart key remote keyless entry fobs, specifically the C1A20 model. Here are some pros and cons of buying a replacement for this fob.

1. Convenience: A remote keyless entry fob offers the convenience of unlocking and locking the doors, opening the trunk, and even starting the engine without having to physically insert the key.

2. Security: The smart key system offers added security as the engine will not start unless the fob is within a certain range.

3. Replacement Parts Availability: Replacement parts for the Infiniti smart key fob are readily available from various online retailers and auto parts stores.

1. Cost: Replacement smart key fobs can be quite expensive, with prices ranging from $100 to $300 or more, depending on the seller and the condition of the fob.

2. Complexity: The smart key system is more complex than traditional key and keyhole systems, which can make repairs more difficult and time-consuming.

3. Battery Life: The fob's battery can drain quickly, especially if the fob is used frequently or if the car is parked in a location with weak signals.

The decision to buy a replacement smart key fob for an Infiniti M35 or M45 depends on the individual's needs and budget. While the convenience and security offered by the fob are significant, the high cost and potential complexity of the system may be a deterrent for some. If the current fob is functioning properly and the battery life is adequate, it may be worth holding off on a replacement. However, if the fob is malfunctioning or the battery is frequently draining, a replacement may be necessary. Ultimately, the cost-benefit analysis will depend on the specific circumstances and priorities of the car owner.

If you do decide to purchase a replacement smart key fob, be sure to research reputable sellers and compare prices to ensure you're getting a fair deal. Additionally, consider purchasing a high-capacity battery to help extend the life of the fob between replacements.
