RMT-TX100A replacement handset for Sony X9000C, X8500C and W800C series
Match the remote code, not just the TV badge
Sony stamped RMT-TX100A on the handset bundled with a large group of its mid-2010s Bravia screens, and that code is the key detail when hunting a replacement. Supported televisions span the KD-55X9000C and KD-65X9000C, the full X8500C spread from 43 through 75 inches, the KD-43X8300C and KD-49X8300C, plus premium models like the KD-75X9100C, KD-65X9300C and KD-75X9400C. The W800 families are included as well, taking in the KDL-50W800C, KDL-55W800C, KDL-43W800D, KDL-50W800D and KDL-55W800D among others. Sony kept this handset in service across two screen families and several price tiers, which is why the compatibility list reads longer than most.
Powered by two AAAs and ready instantly
Setup consists of opening the battery door and inserting two 1.5V AAA cells, which you supply yourself since none come in the box. From that moment the handset runs a compatible Bravia with no programming whatsoever, and the one-touch Netflix key behaves identically to the factory original. One remote control is included in the package. Many buyers grab a unit like this purely as a backup, because a spare that needs zero configuration can be handed to a babysitter or house guest without a word of instruction. The lack of any pairing step also means the unit cannot be locked to a particular television, so it moves between compatible sets freely.
Cross-shopping other Sony handsets
When the code on your dead remote reads differently, The Remote Factory carries the alternatives. This store lists a second Sony RMT-TX100A remote for KD-55X9000C KD-65X9000C under its own page if stock or pricing matters to you. The 2017 generation is handled by the Sony Bravia RMT-TX300E remote for KDL32W660E KD43X7000E, while the intermediate series pairs with the Sony RMT-TX202P replacement for Bravia smart TVs. Between the generations stocked here, nearly every Bravia from the mid-2010s onward has a matching replacement sitting on the same shelf.
What The Remote Factory brings to the order
Because The Remote Factory concentrates on one category, replacement remotes and key fobs for Australian households, a part like this RMT-TX100A substitute is a stocked staple rather than a special order. Items leave the warehouse inside 24 hours, standard post then covers Australia in roughly one to five working days and New Zealand in two to eight. Cards and wallets accepted include Visa, Mastercard, American Express, PayPal, Shop Pay and Apple Pay. Orders are protected by a 30-day return policy, with the crew at contact@theremotefactory.com.au ready to check model lists for you first. For most buyers that means the handset is back on the couch armrest well inside a week of placing the order.
Frequently asked questions
Which Bravia televisions pair with this RMT-TX100A replacement?
Coverage includes the X9000C series such as KD-55X9000C and KD-65X9000C, the X8500C range from KD-43X8500C to KD-75X8500C, the KD-43X8300C and KD-49X8300C, and flagship sets like KD-75X9100C, KD-65X9300C, KD-55X9300C and KD-75X9400C. W800C and W800D models including KDL-43W800C, KDL-50W800C and KDL-55W800D are listed too, so most 2015-era Bravias are accounted for. A quick glance at your TV's rear label confirms the match before you order.
What batteries does the RMT-TX100A replacement take?
It runs on two 1.5V AAA batteries, which are not supplied in the package. Any standard alkaline AAA pair will do the job, and a fresh set is recommended for maximum infrared range. Once the cells are in, the remote is fully operational with no further steps, codes or pairing required on compatible Sony televisions.
Can I use this as a second remote alongside my original?
Absolutely. Infrared remotes do not pair exclusively with a television, so this unit and your factory original can both control the same Bravia interchangeably. Keeping one in the lounge and one in a drawer, or one at a holiday house, is a common approach that avoids panic the next time a handset slips behind the cushions.
What are my options if the remote arrives and does not suit?
Compatibility misses are covered by the 30-day return policy, so you can exchange it for the correct Sony part. Email contact@theremotefactory.com.au with the model number from the back of your television and the code from your original handset, and the right replacement will be identified before the return is even lodged. Dispatch is always within 24 hours.
