Porsche Key Fob Replacement

This unprogrammed remote replaces original keys for 2010 to 2018 Porsche 911, Boxster, Cayenne, Cayman, Macan and Panamera models. It operates at 315 MHz and carries FCC ID KR55WK50138 with part number 7PP-959-753-BQ. Buyers must confirm their original key matches these identifiers before ordering.

OEM Chip and Tested Build

The fob holds an OEM chip and undergoes professional testing before shipment. Buttons are designed for simpler, quicker operation while the housing uses materials intended to extend battery life and improve wear resistance. Water-proof performance is also noted for daily durability.

Locksmith Programming Required

Installation is not a DIY task; the remote must be programmed by a qualified locksmith or dealer. Compatibility cannot be guaranteed without verifying the vehicle's specific requirements first. Incorrect FCC ID or part number matching is the most common reason programming fails.

Questions about this item

How often will the KR55WK50138 fob battery need replacing?

The remote uses a standard coin cell that typically lasts several years; replace it when button range noticeably drops.

What limits the KR55WK50138 range during heavy daily use?

The 315 MHz signal is the first constraint; obstacles or low battery will reduce effective distance before any internal component overheats.

Does the KR55WK50138 generate noticeable heat or noise when carried all day?

No, the fob is passive until a button is pressed and produces no audible noise or perceptible warmth during normal carry.
