MechanMagic Key Fob Remote Replacement Fits for Honda Civic EX Si Hybrid 2006 2007 2008 2009 2010 2011 2012 2013 Acura MDX 2007-2013 (N5F-S0084A)
Quick take
This 4-button keyless entry remote head fob is designed to replace a lost or damaged fob for select Honda Civic and Acura MDX models that use FCC ID N5F-S0084A and related part numbers. It comes with battery and electronics pre-installed, but you will still need the key cut and the remote programmed, and it is not intended for push-start or certain passive entry, proximity, or smart-key setups.
Pros and cons
Pros
- Includes electronics and battery pre-installed, so you can focus on cutting and programming.
- Targeted compatibility for specific Honda Civic (2006 to 2013) and Acura MDX (2007 to 2013) keyless entry systems (FCC ID match).
- 4-button remote design with radio-frequency connectivity and an ergonomic key fob body.
- Programming guidance is straightforward: use a qualified locksmith or dealership.
Cons
- Programming and key cutting are required, adding cost and scheduling time.
- Doesn’t work on push-start vehicles, and it is not for systems like passive entry, passive start, smart key, or proximity.
- Fitment is model- and trim-dependent, so you must verify keyless entry equipment before ordering.
What buyers think
Buyer-review evidence for this key fob replacement is broadly positive, with recurring themes that it performs as expected after professional (or properly done) programming. Multiple comments mention successful pairing and reliable day-to-day operation once the remote and key are cut/programmed for the vehicle. At the same time, one theme to keep in mind is that build quality may feel different from an OEM part, though buyers still describe it as a workable replacement at its price point. Overall, the pattern in feedback points to compatibility and programming success as the main determinants of whether it “just works.”
Who this key fob replacement is for
This remote replacement is a good match if you need a replacement keyless entry fob head for a compatible vehicle and you know your car uses the correct keyless entry setup (not push-start or proximity-based systems). It’s aimed at drivers with Honda Civic models from 2006 through 2013 and Acura MDX models from 2007 through 2013, when the remote’s FCC ID and part-number match your original fob requirements.
Compatibility checklist before you buy
Key fobs can be “look alike” but behave differently depending on the vehicle’s keyless system. Before ordering, confirm:
- FCC ID: N5F-S0084A, N5F-A05TAA.
- Compatible part numbers: 35111-SVA-306 and 35118-TR0-A00.
- Button count: 4 buttons.
- Your vehicle type: it is intended for regular key vehicles with keyless entry, not push-button start vehicles.
If your Civic is not equipped with keyless entry (for example, some DX configurations are noted as not having the keyless system), this remote won’t be able to function as a replacement. If you’re ordering for an Acura MDX or other supported models, double-check the system type so you do not pay for a fob that can’t be programmed for your setup.
Programming and key cutting, what to expect
This fob is not a plug-and-play replacement. It requires the key to be cut and the transmitter to be programmed by a qualified locksmith or a dealership. Plan for that workflow and bring the vehicle identification details your service provider may request (for example, vehicle year, trim, and the original keyless fob information if you have it).
Design and usability notes
The remote is built around a 4-button layout and uses radio frequency connectivity. It’s specified for one CR2 battery, and the unit is described as shipping with the battery and electronics installed, which reduces the amount of DIY prep you need to do.
In practice, the day-to-day “feel” will come down to how well the fob matches your original housing and how successfully the remote is programmed for your vehicle, since those factors drive responsiveness and reliability.
Pros and cons recap
- Best for: Honda Civic (2006 to 2013) and Acura MDX (2007 to 2013) owners who need a 4-button keyless entry remote head fob with the correct FCC ID and part-number match.
- What could be annoying: You’ll need key cutting and programming, and the fob won’t work for push-start and certain proximity or smart-key style systems.
- Value angle: If your vehicle is compatible, buyers generally describe it as a practical replacement that works after programming.
Alternatives to consider
If this one doesn’t match your vehicle’s key system type, your best alternatives are usually determined by your car’s original keyless hardware:
- Look for the correct FCC ID and button count: Many keyless systems require an exact remote specification, so choosing by vehicle year alone can lead to mismatches.
- Use an OEM replacement or dealer-programmed solution: This can simplify compatibility questions if you are unsure about your car’s keyless entry configuration, especially for older models with wiring or trim variations.
Verdict
The MechanMagic 4-button key fob remote head replacement is a solid option when your Honda Civic or Acura MDX is confirmed to match the listed FCC ID and part-number requirements, and when your vehicle uses a keyless entry setup that is compatible with this type of transmitter. The biggest purchase caveat is that programming and key cutting are still required, and push-start or proximity-based systems won’t be supported.
FAQs

No. This remote replacement is described as not working for push-button start vehicles, and it is not intended for passive entry, passive start, smart-key, or proximity system setups.
Do I need programming for this key fob?
Yes. The key must be cut and the transmitter must be programmed by a qualified locksmith or dealership. The remote is not meant to function without that step.
What vehicles is it compatible with?
It’s intended for select Honda Civic models from 2006 to 2013 and Acura MDX models from 2007 to 2013, when the keyless entry system matches the listed FCC ID (N5F-S0084A, N5F-A05TAA) and the compatible part numbers (35111-SVA-306, 35118-TR0-A00).
Does it include a battery?
Yes. The battery and electronics are described as pre-installed, and it’s specified to use a CR2 battery.
Is it the right choice if my car has passive entry or proximity?
Likely not. This key fob replacement is described as not supporting those system types, so you should verify your vehicle’s keyless setup before purchasing.
