5-Button 433MHz Proximity Fob

This replacement keyless entry remote operates at 433MHz with a 46 chip and includes a CR2032 battery. It provides remote locking, unlocking, panic, trunk release and remote engine start functions for compatible vehicles. The unit combines the fob and integrated door key in a single black plastic and metal housing measuring 6.5 by 4.1 centimetres.

Sustained Daily Operation

The fob transmits at 433MHz for reliable communication with the vehicle receiver during repeated lock, unlock and remote start cycles. Its built-in 46 chip maintains cryptographic handshake integrity over extended use without signal degradation. The included 3V coin cell powers the transmitter consistently until replacement is needed.

Professional programming and key cutting by a qualified locksmith or dealership are mandatory before the remote will function.

Questions about this item

Does the CR2032 battery drain quickly when the fob is used daily for remote start?

The fob uses a standard CR2032 coin cell; typical life is months to years depending on how often the five buttons are pressed.

Do I need a working original fob already paired to the vehicle to add this replacement?

Yes — a currently programmed fob is required before a locksmith or dealer can pair this HYQ1EA unit.

Will this 433 MHz fob interfere with the factory system on my 2020 Silverado 1500?

It operates on the same 433 MHz frequency and 46 chip as the OE part numbers 13529632 and 13508398, so it integrates without conflict.
